 laborate on a semi-classical Hamiltonian approach to describe the QGP prod
 uction mechanism in real time based upon the existence of a homogeneous in
 itial state being a non-trivial QCD ground-state. An effect ala parametric
  resonance leading to a decay of the homogeneous gluon condensate into inh
 omogeneous gluon plasma is thought to be a possible driver of QGP producti
 on in QCD.\n\nhttps://indico.fysik.lu.se/event/1065/contributions/65/

DESCRIPTION:Speakers: Konrad Tywoniuk (Bergen U.)\n\nHard probes\, and in 
 particular jets\, are at the same time both promising and challenging tool
 s for probing the hot and dense nuclear matter created in high-energy heav
 y-ion collisions at the RHIC and LHC. Radiative processes in the medium le
 ad to a redistribution of energy within the jet cone and an enhanced energ
 y leakage out of it. These modifications are governed by the interplay of 
 the relevant momentum- and time-scales\, and are sensitive to the way part
 onic fluctuations within the jet are resolved by the medium. Mapping out a
 ll relevant regimes of jet-medium interactions onto the Lund kinematical p
 lane\, we establish a probabilistic picture of the fragmentation in the fo
 rm of a generating functional (GF). In contrast to the GF in vacuum\, in m
 edium it contains terms describing fragmentation at short and long time-sc
 ales\, compared to the medium scales\, and the transition between them. Du
 e to the mismatch between real and virtual emissions\, the GF is normalize
 d to the collimator function that describes how jet substructures are quen
 ched and can be measured from the inclusive jet spectrum in heavy-ion coll
 isions. We put a special emphasis on the role of color coherence for hard\
 , small-angle fluctuations.\n\nhttps://indico.fysik.lu.se/event/1065/contr

 , most prominently a description of the ridge in pp collisions. Since Lund
  strings also connect the hardest fragment of a jet to beam remnants\, sho
 ving the connecting strings will affect jet observables as well. Similarit

DESCRIPTION:Speakers: Carlos Salgado\, Gavin Salam\, Guilherme Milhano\, L
 iliana Apolinário (LIP Lisbon)\n\nTop quarks have been recently proposed 
 as a unique probe to determine the space-time evolution of the medium that
  is created in heavy-ion collisions [1]. In particular\, they allow an app
 roximate determination of the time at which the top’s decay products sta
 rt interacting with the QGP\, making this channel most sensitive to the la
 te time dynamics of the produced medium. This is achieved by using the had
 ronic decay chain of the top quark: in addition to the finite lifetimes of
  the top and W-boson\, the time-delay in the interaction of the (colour-si
 nglet) W-boson’s decay products with the medium adds to a finite total t
 ime-delay that can be applied to probe different QGP timescales. \nTop qua
 rks have already been measured in nuclear collisions. With the forthcoming
  HL-LHC and HE-LHC\, the increase in luminosity and energy can be further 
 explored to use top quark observables as a unique probe of the QGP. In thi
 s talk\, we show the latest projections for the use of this particular cha
 nnel in both PbPb and lighter ions collisions in these two setups.\n\n[1]

DESCRIPTION:Speakers: Konrad Tywoniuk\, Gergely Gabor Barnafoldi\, Denes M
 olnar\, Adam Takacs (Bergen U.)\n\nRelativistic viscous hydrodynamics calc
 ulations can describe a wide range of observables in relativistic heavy io
 n collisions. However\, many studies suggest that the hot and dense system
  created is not in local thermal equilibrium\, resulting in a contradictio
 n for the applicability of hydrodynamics. In hydrodynamic calculations\, a
  crucial step is to convert the fluid fields into observable particles. Th
 e most common\napproach is to use the Cooper-Frye formula\, which assumes 
 thermal (Boltzmann/Bose/Fermi) distributions at the conversion. In this ta
 lk\, I show how local equilibrium distributions of the Tsallis form can af
 fect observables\, resulting in non-exponential particle distributions and
  a viscous-like suppression of the anisotropic flow. By comparing the calc
 ulation to experimental data\, I will estimate the degree of non-\nBoltzma
 nn effects on the freeze-out surface.\n\nhttps://indico.fysik.lu.se/event/

DESCRIPTION:Speakers: Vladimir Kovalenko (St.Petersburg State U.)\n\nThe m
 ultiplicity dependence of the mean transverse momentum as well as strangen
 ess and multi-strangeness production is studied in the framework of two mo
 dels: dipole-based Monte Carlo model with string fusion [1-2]\, and extend
 ed multi-pomeron exchange model [3-4]. The first model allows the unifying
  description of pp\, pA and AA collisions [5]. The partonic interactions a
 re described as collisions of dipoles. The hardness of the collision is de
 termined by transverse size of the colliding dipoles. The production of th
 e observed particles is implemented in the string mechanism\, taking into 
 account string fusion [6-7]. The second model [3-4] is based on Regge-Grib
 ov approach. The model includes string collectivity\, parametrized by one 
 parameter\, beta\, which is determined by data on pt-multiplicity correlat
 ion at wide energy range.\nFor the particles species discrimination\, both
  models use the modified Schwinger mechanism [8]\, where the effective str
 ing tension\, according to the string fusion prescription\, depends on the
  string density. We show that two effects contribute to the transverse mom
 entum: the hardness of the partonic collision\, and the modification of th
 e string tension. Only second effect leads to the modification of strangen
 ess and multi-strangeness production. Taking it into account allows one to
  describe the experimental data [9] at LHC energy.\n\n[1] V. N. Kovalenko\

DESCRIPTION:Speakers: Kristjan Gulbrandsen (NBI)\n\nOne of the most used m
 ethods to compute flow coefficients in high-energy particle collisions is 
 the Q-cumulant method. The method employs the mathematical concept of a cu
 mulant which is meant to identify correlations to some order (between more
  particles in this case). For this reason\, it is often said that the meth
 od removes lower order non-flow effects. A semi-theoretical study has been
  done to show that this is not (by design) true. Additionally\, other effe
 cts of the particle distribution function can produce artificial flow sign
 als. Such effects are demonstrated and discussed.\n\nhttps://indico.fysik.

DESCRIPTION:Speakers: Joao Barata (Santiago de Compostela)\n\nMost jet que
 nching models predict that\, at the parton level\, the quark to gluon ener
 gy loss due to in-medium interactions scales with the ratio of the corresp
 onding Casimirs $C_F/C_A$. However\, in the jet framework\, one expects a 
 violation of this scaling due to the finite extension of the jet. In this 
 talk\, I will present results from a Monte Carlo study of calibrated Z+jet
 s events which allow addressing this problem. The results presented here s
 how an interesting scaling violation which indicates that gluon and quark 
 jets are much more similar in medium than the corresponding partons. In ad
 dition\, a parametrization of the average energy loss for quarks and gluon
 s and for its  variance is provided. Such a parametrization can prove usef
 ul to computing observables for in-medium events without needing a full Mo
 nte Carlo simulation.\n\nhttps://indico.fysik.lu.se/event/1065/contributio

DESCRIPTION:Speakers: Ilkka Helenius\n\nTraditionally jet production in di
 fferent collision systems has been used to study different physics: jet qu
 enching in AA\, initial-state nuclear modifications in pA and pQCD baselin
 e in pp. There are\, however\, recent observations of similar collective e
 ffects in all these systems. This challenges the picture where the measure
 ments in these different systems would provide information only on well-se
 parated physics phenomena. In addition to these widely-studied collision s
 ystems\, it is also possible to study photon-proton and photon-nucleus int
 eractions in ultra-peripheral collisions (UPCs) at the LHC. These photon-i
 nduced processes could offer new insights on the collective phenomena and 
 provide a clean environment to study purely initial-state effects. In this
  talk we discuss how these processes can be simulated with Pythia 8 genera
 l-purpose Monte Carlo event generator by applying the recent photoproducti
 on framework. As an application\, we study the potential of photo-nuclear 
 dijets in PbPb collisions at the LHC to further constrain nuclear PDFs. In
  addition\, we introduce our dynamical rapidity gap survival model for har
 d diffraction which is now implemented also for photoproduction in Pythia 
 8\, and present predictions for diffractive dijet production in UPCs at th
 e LHC.\n\nhttps://indico.fysik.lu.se/event/1065/contributions/77/

DESCRIPTION:Speakers: Anton Motornenko (Frankfurt U.)\n\nThe kaon to pion 
 ratio K^+/\\pi^+ and the scaled variance \\omega^- for fluctuations of neg
 atively charged particles are studied within the statistical hadron resona
 nce gas (HRG) model and the Ultra relativistic Quantum Molecular Dynamics 
 (UrQMD) transport model. The calculations are done for p+p\, Be+Be\, Ar+Sc
 \, and Pb+Pb collisions at the CERN Super Proton Synchrotron energy range 
 to reveal the system size dependence of hadron production. For the HRG cal
 culations the canonical ensemble is imposed for all conserved charges. In 
 the UrQMD simulations the centrality selection in nucleus-nucleus collisio
 ns is done by calculating the forward energy E_{\\rm F} deposited in the P
 rojectile Spectator Detector\, and the acceptance maps of the NA61/SHINE d
 etectors are used. The role of centrality selection on fluctuation measure
 s is studied in detail.  A comparison of the HRG and UrQMD results with  t
 he data of the  NA61/SHINE Collaboration is done. To understand a differen
 ce of the event-by-event fluctuations in p+p and heavy ion collisions the 
 centrality selection procedure in the sample of all inelastic p+p events i
 s proposed and analyzed within the UrQMD simulations.\n \nReferences:\n\n[

DESCRIPTION:Speakers: Christopher Plumberg (Lund U.)\n\nParticle interfero
 metry - also known as Hanbury Brown-Twiss (HBT) interferometry -  is a mea
 surement technique based on momentum-space correlations between identical 
 particles which has proven to be an indispensable tool in studying the spa
 ce-time evolution of femtoscopic collision systems.  In particular\, HBT i
 nterferometry allows one to classify these collision systems on the basis 
 of their collision geometry.  This\, in turn\, provides a useful aid to ca
 librating things such as jet-quenching analyses in both large and small co
 llision systems\, where the precise geometry of the system plays a crucial
  role in the interpretation of experimental results.\n\nIn this talk\, I d
 escribe some recent and ongoing efforts to connect the techniques of HBT i
 nterferometry with the question of QGP medium formation in heavy-ion colli
 sions and high multiplicity hadron-hadron collisions\, some of which are d
 irectly relevant to the goal of understanding jet-quenching in collision s
 ystems of various sizes.  Specifically\, I will show how hydrodynamic pred
 ictions for the space-time geometry can be tested using HBT\, and I will d
 iscuss some current work to enable similar predictions to be made using th
 e MC event generator formalism of Pythia/Angantyr for the modeling of high
 -energy collision systems.\n\nhttps://indico.fysik.lu.se/event/1065/contri

 ativistic heavy ions are used to create strongly interacting matter in the
  regime of high-energy densities and temperatures. Under these conditions 
 color confinement of quarks and gluons in hadrons breaks down  and a new s
 tate of matter called Quark-Gluon Plasma is formed. Properties of this med
 ium can be inferred  based on observed modifications of produced jets.  Re
 cently\, jet analyses have developed new tools to study jet properties mor
 e differentially.  These observables are based on hadron-jet correlations 
 or jet-shape and jet-substructure measurements. The talk will review recen
 t results from these jet analyses peformed in ALICE.\n\nhttps://indico.fys

DESCRIPTION:Speakers: Michal Sumbera (NPI Prague)\n\nThe extreme energy de
 nsities generated in ultra-relativistic heavy ion collisions produce a sta
 te of matter that behaves surprisingly like a fluid\, with exceptionally h
 igh temperature and low viscosity. Non-central collisions have angular mom
 enta of the order of 1\,000ћ\, and the resulting fluid may have a strong 
 local rotational structure. Spin–orbit coupling can lead to preferential
  orientation of particle spins along the direction of rotation. I will pre
 sent STAR measurements (Nature 548 (2017) 62\, arXiv:1701.06657) of an ali
 gnment between the global angular momentum of a non-central collision and 
 the spin of emitted particles\, revealing that the fluid produced in heavy
  ion collisions is the most vortical system so far observed. I will also b
 riefly discuss observable effects due to strong magnetic fields produced i
 n ultra-relativistic heavy ion collisions related to the restoration of fu
 ndamental symmetries of quantum chromodynamics.\n\nhttps://indico.fysik.lu

DESCRIPTION:Speakers: Lucia Oliva (GSI\, Darmstadt)\n\nThe recent experime

 asma even in small systems such as proton-nucleus collisions. In the early
  stage of relativistic heavy ion collisions extremely intense magnetic fie
 lds\, with\na magnitude up to 5-50 m_π^2\, are produced\; in asymmetric c
 ollisions\, and in proton-induced reactions in particular\, not only the m
 agnetic field but also the electric field is very high. Moreover\, in asym
 metric colliding systems the particle rapidity distributions are strongly 
 asymmetric inside the overlap region. By means of microscopic calculations
  within the Parton-Hadron-String Dynamics (PHSD) approach we study the dis
 tributions of electromagnetic fields in central p+Au collisions and invest
 igate the influence of these fields on final hadronic observables\, such a
 s particle distributions and flow harmonics.\n\nhttps://indico.fysik.lu.se

DESCRIPTION:Speakers: Elena Bratkovskaya (GSI\, Darmstadt)\n\nWe present t

 ach which is a microscopic covariant dynamical model for strongly interact
 ing systems formulated on the basis of Kadanoff-Baym equations for Green's
  functions in phase-space representation (in 1st order gradient expansion 
 beyond the quasi-particle approximation). The approach consistently descri
 bes the full evolution of a relativistic heavy-ion collision from the init
 ial hard scatterings and string formation (based on LUND string model) thr
 ough the dynamical deconfinement phase transition to the strongly-interact
 ing quark-gluon plasma (sQGP) as well as hadronization and the subsequent 
 interactions in the expanding hadronic phase. The PHSD approach has been a
 pplied to p+p\, p+A and A+A collisions from lower SIS to LHC energies and 
 been successful in describing a large number of experimental data includin
 g single-particle spectra\, collective flow and electromagnetic probes. Th
 e highlights of the PHSD results will be presented with the focus on charm
  production.\n\nhttps://indico.fysik.lu.se/event/1065/contributions/102/

  of the collisions of heavy nuclei at relativistic energies have establish
 ed the properties of the quark–gluon plasma (QGP)\, a state of hot\, den
 se nuclear matter in which quarks and gluons are not bound into hadrons. I
 n this state\, matter behaves as a nearly inviscid fluid that efficiently 
 translates initial spatial anisotropies into correlated momentum anisotrop
 ies among the particles produced\, creating a common velocity field patter
 n known as collective flow. In recent years\, comparable momentum anisotro
 pies have been measured in small-system proton–proton (p+p) and proton
 –nucleus (p+A) collisions\, despite expectations that the volume and lif
 etime of the medium produced would be too small to form a QGP. Here we rep
 ort on the observation of elliptic and triangular flow patterns of charged
  particles produced in proton–gold (p+Au)\, deuteron–gold (d+Au) and h
 elium–gold (3He+Au) collisions at a nucleon–nucleon centre-of-mass ene
 rgy sqrt(s_NN)=200 GeV. The unique combination of three distinct initial g
 eometries and two flow patterns provides unprecedented model discriminatio

DESCRIPTION:Speakers: Ranjit Nayak (IIT Bombay)\n\nThe p-p collisions at h
 igh multiplicity at LHC show small scale collective effects similar to tha
 t observed in heavy ion collisions such as enhanced production of strange 
 and multi-strange hadrons\, long range azimuthal correlations\, etc. The o
 bservation of strangeness enhancement in p-p collisions at 7 TeV and 13 Te
 V as measured by ALICE experiment is explored using Pythia8 event generato
 r within the framework of microscopic rope hadronization model which assum
 es the formation of ropes due to overlapping of strings in high multiplici
 ty environment. The spectral shape and its hardening with multiplicity is 
 well described by the model. The mechanism of formation of ropes also desc
 ribed the observed experimental strangeness enhancement for higher multipl
 icity classes in p-p collisions at 7 TeV and 13 TeV. The enhancement with 
 multiplicity is further investigated by studying the mean pT () and the in
 tegrated yields () of strange and multi-strange hadrons and comparing the 
 predictions to the mea- sured data at LHC for 7 TeV and 13 TeV.\n\nhttps:/
