  46. 50. Absorption of phi mesons in proton-nucleus collisions
    Mr Henry Schade (FZD)
    Recent experiments of the ANKE collaboration concerning the phi meson production in pA-reactions p (2.83 GeV) + C, Cu, Ag and Au are appropriate for the absorptive phi-N interaction within the trancparency ratio. With the aim of analyzing the amount of phi absorption we applied our well confirmed transport model of Boltzmann-Ühling-Uhlenbeck (BUU) type on this scenario. The results seem to...

  47. 67. Charmonium production and elliptic flow in heavy ion collisions
    Prof. Che-Ming Ko (Texas A&M University)
    Using a two-component model for J/Ψ production, which includes both from initial hard nucleon-nucleon scattering and from regeneration in the produced quark-gluon plasma, we have studied the nuclear modification factor RAA and elliptic flow v2 of J/Ψ in Au+Au collision at sNN1/2=200 GeV. For the expansion dynamics of produced hot dense matter, we have introduced a schematic fireball model with...

  48. 51. Cold quark stars from hot lattice QCD
    Mr Robert Schulze (Forschungszentrum Dresden-Rossendorf)
    Based on a quasiparticle model for \beta stable and electrically neutral deconfined matter we address the possibility of pure quark stars. The model is adjusted to recent hot lattice QCD results for 2+1 flavors with almost physical quark masses. Using stability and binding arguments general statements can be made concerning the existence of such compact stellar objects.

  50. 46. Critical opalescence - an optical signature of the QCD critical point
    Prof. Tamás Csörgő (MTA KFKI RMKI and Harvard University)
    Four possible scenarios are considered for a transition from a quark-gluon matter to hadronic matter, and their corresponding correlation signatures are discussed. Four criteria are highlighted for a definitive experimental search for a QCD critical point. An old-new experimental measure, the optical opacity (or its inverse the nuclear attenuation length) is determined, in terms of a...

  51. 61. Energy and system-size dependence of the chiral magnetic effect
    Prof. Viacheslav Toneev (Dubna, Joint Institute for Nuclear Research)
    The energy dependence of the local CP violation in Au+Au and Cu+Cu collisions is estimated within a simple phenomenological model. Predictions for LHC and SPS energies are given. Evolution of the magnetic field in heavy-ion collisions is discussed also.

  53. 6. Flow-Driven Conical Emission in Ultrarelativistic Heavy-Ion Collisions
    Dr Barbara Betz (Columbia University)
    We use (3+1)-dimensional hydrodynamic simulations to describe the propagation of a jet through an opaque medium and to investigate the underlying jet-medium interactions. The impact of different energy and momentum loss scenarios, of different jet velocities, and system sizes are analyzed. We will discuss if the particle correlations measured at the Relativistic Heavy Ion Collider...

  54. 63. Hadron production in a parton cascade modell with non-additive energy composition
    Karoly Urmossy (RMKI KFKI, ELTE)
    Identified particle spectra stemming from pp->hX and AA->hX reactions fit well to a cut-power law formula for various collision energies and wide transverse momentum range. This formula can be obtained as the equilibrium distribution of quasi particles having non-additive energy composition. Real nucleus collisions are however non-equilibrium processes. In this talk I discuss hadron production...

  55. 55. HBT radii from the UrQMD transport approach at different energies
    Mr Gunnar Gräf (Frankfurt Institute for Advanced Studies (FIAS), University of Frankfurt)
    We use the non-equilibrium transport approach Ultra-relativistic Quantum Molecular Dynamics (UrQMD) [1] to compute the dynamics of heavy ion collisions up to LHC energies. From this model we obtain directly the full phasespace distribution of all particles at the kinetic freeze out. By applying the Correlation After Burner (CRAB) [2] of Scott Pratt we extract the two-particle correlation...

  56. 65. Holography vs Tomography of the Hot and Cold Baryonic Matter
    Prof. Miklós Gyulassy (Columbia University)
    The two major competing paradigms for jet-medium interactions at RHIC and LHC are perturbative pQCD and higher dimensional holographic hQCD. I discuss why current RHIC data favor hQCD holography to pQCD tomography by a score of 2-to-1 as of today. hQCD does a remarkable robust job correlating bulk flow and heavy quark quenching observables while pQCD does a better job describing light quark...

  57. 47. Hybrid approaches to heavy ion collisions and future perspectives
    Prof. Marcus Bleicher (FIAS, University of Frankfurt)
    We discuss recent developments in the area of hybrid approaches to the simulation of heavy ion reactions at relativistic energies. Focus will be on the exploration of different equations of state and potential signature of the QGP. The talk will also address some open questions for future developments, like multi-particle interactions and hadronisation.

  58. 52. Influence of the Polyakov loop on the chiral phase transition in the two flavor chiral quark model
    Dr Zsolt Szep (Statistical and Biological Physics Research Group of the Hungarian Academy of Sciences)
    The chiral quark model consisting of the sigma and pion mesons and the constituent quarks propagating on the constant background of a temporal gauge field is solved at finite temperature and baryon chemical potential. Using an expansion in the number of flavors, both the chiral limit and the case with physical pion mass are studied. The location of the critical end point in the mu-T...

  59. 62. Interplay between chiral and deconfinement phase transition
    Prof. Mei Huang (IHEP,CAS)
    The interplay between chiral restoration and deconfinement phase transition is discussed. In the Polyakov-loop NJL model, the relation between the two phase transitions is much parameter dependent, the chiral restoration can happen earlier or latter than the deconfinement phase transition, also the two phase transitions can coincide with each other. We use the dressed Polyakov loop as...

  60. 68. Lattice gauge theory with fluctuating temperature
    Prof. Zsolt Schram (University of Debrecen)
    We study the possibility to implement the canonical Tsallis distribution for lattice field theory simulations. Formally, the application of the Tsallis distribution can be interpreted as introducing a fluctuating temperature. We give arguments for the approach and present our simulation method as well as our first numerical results in determining the equation of state for pure SU(2)...

  62. 4. Meson fluctuations and thermodynamics of the Polyakov loop extended quark-meson model.
    Dr Vladimir Skokov (GSI, Darmstadt, Germany)
    Thermodynamics and the phase structure of the Polyakov loop-extended two flavor chiral quark-meson model (PQM) are explored. The analysis of the PQM model is based on the functional renormalization group (FRG) method. An appropriate truncation of the effective action with quarks coupled to background gluonic fields is introduced. Within this scheme, we derive the renormalization group flow...

  64. 77. Microsecond Universe to Neutron Star - LHC, RHIC onto FAIR
    Prof. BIKASH SINHA (Variable Energy Cyclotron Centre, Dept. of Atomic Energy, 1/AF, Bidhan Nagar, Kolkata-700 064, India)
    The universe, microseconds after the Big Bang consisted of Quarks, Gluons, leptons and photons. Possible remnants from that epoch can be MACHO type of dark objects about the size of the Jupiter. One partial source of dark energy could be the orphan quarks left over from that epoch. In a typical phase diagram early universe corresponds to low baryon density but very high temperature. Neutron...

  65. 49. Multi-particle interactions within UrQMD
    Dr Gerhard Burau (FIAS)
    A mechanism for locally density-dependent dynamic parton rearrangement and fusion has been implemented into the Ultra-relativistic Quantum Molecular Dynamics (UrQMD) approach. The same mechanism has been previously built in the Quark Gluon String Model (QGSM). This rearrangement and fusion approach based on parton coalescence ideas enables the description of multi-particle...

  66. 0. Nonadditive Entropy and Nonextensive Statistical Mechanics - Concepts and Applications
    Prof. Constantino Tsallis (Centro Brasileiro de Pesquisas Fisicas)
    The realm of Boltzmann-Gibbs statistical mechanics, based on the standard additive entropy, essentially concerns ergodic systems, Markovian-like processes, linear Fokker-Planck equations, exponential behaviors of relevant physical, geometrical and dynamical quantities, the central limit theorem. What can be done when such simplifying hypothesis are not satisfied? The nonadditive entropy Sq,...

  67. 3. Nonextensive critical effects in relativistic nuclear mean field models
    Prof. Grzegorz Wilk (The Andrzej Soltan Institute for Nuclear Studies)
    The critical phenomena in strongly interaction matter are generally investigated using the mean-field model and are characterized by well defined critical exponents. However, such models provide only average properties of the corresponding order parameters and neglect altogether their possible fluctuations. Also the possible long range effect are neglected in the mean field approach. Here...

  68. 66. Propagation of vector-meson spectral-functions and dilepton production at SIS18 energies
    Dr György Wolf (RMKI KFKI)
    The time evolution of vector-meson spectral-functions is studied within a kinetic theory approach. We implement this formalism in a BUU type transport model. Applications focus on $\rho$ and $\omega$ mesons being important pieces for the interpretation of the di-electron invariant mass spectrum measured by the HADES collaboration for the reaction C+C at 2 AGeV bombarding energy. Since...

  69. 69. QCD Green's Functions and Phases of Strongly Interacting Matter
    Prof. Reinhard Alkofer (Univ. Graz)
    The knowledge of Landau gauge QCD Green's functions at zero temperature and density as well as their relation to confinement, dynamical chiral symmetry breaking, and the axial anomaly are briefly reviewed. The application of functional methods to the QCD phase transitions is discussed, and resulting properties of some phases are presented.

  70. 60. Quark Number Scaling in Fluid Dynamics and Hadronization via Quarkyonic Matter
    Prof. Laszlo P. Csernai (University of Bergen)
    The observed Constituent Quark Number Scaling of the flow parameter, v_2, for different mesons and baryons is instinctively a proof for collective flow development in quark gluon plasma. Fluid dynamical models assuming phase and chemical equilibrium during all stages cannot account for the observed scaling, while hybrid models with recombination into hadrons can in a limited p_t-range....

    Mr Robert Vertesi (MTA KFKI RMKI)
    PHENIX and STAR data on the intercept parameter of the two-pion Bose-Einstein correlation functions in $\sqrt{s_{NN}}= 200$ GeV Au+Au collisions are analyzed in terms of six different models of hadronic multiplicities. To describe this combined PHENIX and STAR dataset, an in-medium $\eta^\prime$ mass reduction of at least 200 MeV is needed, at the 99.9 \% confidence level, in the considered...

  75. 53. Study of particle production coming from quark and gluon jets in proton-proton collisions
    Sona Pochybova (MTA KFKI RMKI)
    The study of particle production inside jets makes it possible to address the fragmentation properties of the leading parton depending on its flavour. We investigate whether different fragmentation properties of quarks and gluons affect identified particle spectra.\\ We present a systematic study of $K$, $p$ and $\pi$ production at RHIC, Tevatron and LHC energies. Through the study of...

    Dr Jacek Rozynek (SINS, Warsaw, Poland.)
    Our model calculations performed in the frame of relativistic mean field (RMF) approach shows how important are the modifications of nucleon mass (particularly for those models with stiff Equation o State (EoS)). They allow to explain the EMC effect in saturation and restore the momentum sum rule badly violated by the nuclear parton structure in nuclear medium for finite pressure. The finite ...

    The Compressed Baryonic Matter (CBM) experiment [1] is being planned at the international research center FAIR [2], under realization next to the GSI laboratory in Darmstadt, Germany. Its physics programme addresses the QCD phase diagram in the region of highest net baryon densities. Of particular interest are the expected first order phase transition from partonic to hadronic matter, ending...

  82. 1. The nuclear liquid-gas phase transition at large N_c
    Dr Giorgio Torrieri (JW Goethe Universitat, Frankfurt)
    We examine the nuclear liquid-gas phase transition at large number of colors (N_c) within the framework of the Van Der Waals (VdW) model. We argue that the VdW equation is appropriate at describing inter-nucleon forces , and discuss how each parameter scales with N_c. We demonstrate that N_c=3 is not large with respect to the other dimensionless scale relevant to baryonic matter, the number of...

    Dr Péter Ván (MTA KFKI RMKI, Dep. of Theoretical Physics)
    Hydro and Transport Models I.
    In the presentation the concept of temperature in relativistic thermodynamics is shortly surveyed and argued that the historical paradoxes are connected to the stability and causality issues of relativistic hydrodynamic theories. It is shown that a choice of "flow frames" (e.g. Eckart or Landau-Lifshitz), that is the definition of the velocity field, can partially hide the problematic aspects...

  85. 64. Towards Quantum Transport for Central Nuclear Reactions
    Prof. Pawel Danielewicz (NSCL/Cyclotron Laboratory, Michigan State University)
    Striving to develop a practical approach for nuclear collisions, based on nonequilibrium Green's functions, we start out by considering collisions of slabs in one dimension, within the mean-field approximation of the Green’s-function method. In the latter case, the dynamics is self-consistently described in terms of a single-particle density-matrix for the colliding system. We concentrate on...

  86. 83. Transport with unstable particles
    Dr Antal Jakovac (BME Institute pf Physics)
    Hydro and Transport Models I.
    The small value of the shear viscosity to entropy density ratio suggests a strongly interacting quark matter where the elementary excitations are far from being small-width quasiparticles. In this talk I suggest an approach how the transport coefficients can be calculated in systems with broad spectral functions. It will be shown that the transport coefficients are naturally small, and, in...

  87. 81. Tsallis Distribution in High-energy Heavy Ion Collisions
    Dr Gergely Gábor Barnaföldi (MTA KFKI RMKI)
    Non-extensive thermodynamics is a novel approach to fields in high energy physics. The low and intermediate transverse momentum spectra are extremely well reproduced by the Tsallis-Pareto distribution however, the physical origin of the Tsallis parameter is still an unsettled question. Understanding hadronization processes in heavy-ion collisions requires more detailed tests, especially at...
