Diffusion processes involving multiple conserved charges: a first study from kinetic theory and implications to the fluid-dynamical modeling of heavy ion collisions
Jan A. Fotakis, Moritz Greif, Gabriel Denicol +2
The bulk nuclear matter produced in heavy ion collisions carries a multitude of conserved quantum numbers: electric charge, baryon number, and strangeness. Therefore, the diffusion…
Equation of state of QCD matter within the Hagedorn bag-like model
Volodymyr Vovchenko, Mark I. Gorenstein, Carsten Greiner +1
The QCD equation of state at finite temperature and densities of conserved charges is considered in the framework of a Hagedorn bag-like model, incorporating both the finite sizes…
Bulk viscosity in strong and electroweak matter
Abdel Nasser Tawfik, Carsten Greiner
For temperatures ranging from a few MeV up to TeV and energy density up to GeV/fm, the bulk viscosity is calculated in non-perturbation (up, down, strange…
Calculation of anisotropic transport coefficients for an ultrarelativistic Boltzmann gas in a magnetic field within a kinetic approach
Zhengyu Chen, Carsten Greiner, Anping Huang +1
According to the Kubo formulas we employ the (3+1)-d parton cascade, Boltzmann approach of multiparton scatterings (BAMPS), to calculate the anisotropic transport coefficients (she…
The Shear Viscosity to Entropy Density Ratio of Hagedorn States
Jan Rais, Kai Gallmeister, Carsten Greiner
The fireball concept of Rolf Hagedorn, developed in the 1960's, is an alternative description of hadronic matter. Using a recently derived mass spectrum, we use the transport model…
Critical point signatures in the cluster expansion in fugacities
Volodymyr Vovchenko, Carsten Greiner, Volker Koch +1
The QCD baryon number density can formally be expanded into a Laurent series in fugacity, which is a relativistic generalization of Mayer's cluster expansion. We determine properti…
Polyakov linear-sigma model in mean-field approximation and optimized perturbation theory
Abdel Nasser Tawfik, Carsten Greiner, Abdel Magied Diab +2
We compare results from the Polyakov linear-sigma model (PLSM) in optimized perturbation theory (OPT) with the mean-field approximation (MFA). At finite temperatures and chemical p…
Kinetic freeze-out temperature from yields of short-lived resonances
Anton Motornenko, Volodymyr Vovchenko, Carsten Greiner +1
A method to determine the kinetic freeze-out temperature in heavy-ion collisions from measured yields of short-lived resonances is presented. The resonance production is treated in…
Effects of fluctuations and color-neutrality in a finite volume
Christian Spieles, Marcus Bleicher, Carsten Greiner
We investigate properties of strongly interacting matter in a schematic model, based on the combined degrees of freedom of a non-interacting hadronic phase and a non-interacting de…
Kinetic approach to a relativistic BEC with inelastic processes
Richard Lenkiewicz, Alex Meistrenko, Hendrik van Hees +3
The phenomenon of Bose-Einstein condensation is investigated in the context of the Color-Glass-Condensate description of the initial state of ultrarelativistic heavy-ion collisions…
Kramers's escape rate problem within a non-Markovian description
Benjamin Schüller, Alex Meistrenko, Hendrik van Hees +2
We compare the thermal escape rates of a Brownian particle, initially trapped into one of the two wells of an asymmetric double-well potential, for thermal Markovian and non-Markov…
Nucleosynthesis in heavy-ion collisions at the LHC via the Saha equation
Volodymyr Vovchenko, Kai Gallmeister, Jürgen Schaffner-Bielich +1
The production of light (anti-)(hyper-)nuclei in heavy-ion collisions at the LHC is considered in the framework of the Saha equation, making use of the analogy between the evolutio…
Importance of initial and final state effects for azimuthal correlations in p+Pb collisions
Moritz Greif, Carsten Greiner, Björn Schenke +2
We study the influence and interplay of initial state and final state effects in the dynamics of small systems, focusing on azimuthal correlations at different multiplicities. To t…
Theoretical Review of Charmonium Production with Different in the Hot Medium
Baoyi Chen, Carsten Greiner
Charmonia with different transverse momentum usually comes from different mechanisms in the relativistic heavy ion collisions. This work tries to review the theoretical studi…
