Classical models of heavy ion collisions
We study the effects of the nuclear equation of state (EOS) on intermediate energy heavy-ion collisions using classical microscopic models. The role of the EOS on the disassembly of expanding, hot nuclear matter, as well as the experimental data on multi-fragmentation and collective flow phenomena, …

Pion Production in Relativistic Heavy Ion Collisions
In der vorliegenden Arbeit wird die Pionenproduktion verschiedener Systeme (Ca+Ca, Ru+Ru, Zr+Zr und Au+Au) bei drei verschiedenen Strahlenergien (400, 1000 und 1500 AMeV) untersucht. Die Experimente wurden mit dem FOPI Detektor am Schwerionen Synchrotron (SIS) der Gesellschaft fuer …

Hadronization in Ultra-Relativistic Heavy Ion Collisions
… proposed mechanisms for the dynamical hadronization transition in both ultra-relativistic heavy-ion collisions and the very early universe. We develop very general criteria for hydrodynamical stability and apply them to a number of proposed solutions. We find that the hadronization is …

Rescattering and fluctuations in ultrarelativistic heavy-ion collisions
We study ultra-relativistic heavy-ion collisions using, as far as possible, known physics and simple assumptions. One focus is on the measurable effects of rescattering of produced particles in the colliding nuclei. Two models for proton-nucleus collisions are presented, one built from independent …

Dynamics of pions in ultrarelativistic heavy ion collisions
In an ultrarelativistic collision of heavy nuclei, such as 197Au, at an energy Vs above roughly 10 GeV per nucleon pair, nuclear transparency effects are expected to give rise to a baryon-poor central region. Matter in the central region can begin either as a pion fluid or as a quark-gluon plasma, …

Jet Quenching in Relativistic Heavy Ion Collisions at the LHC
Jet production in relativistic heavy ion collisions is studied using Pb+Pb collisions at a center of mass energy of 2.76 TeV per nucleon. The measurements reported here utilize data collected with the ATLAS detector at the LHC from the 2010 Pb ion run corresponding to a total integrated luminosity …

Flux corrected transport applied to hydrodynamics for heavy ion collisions
… FCTHydro, a ROOT package, and its application to hydrodynamic simulations through the packages RelHydro and Nonideal xy. These packages aim to provide the broader heavy ion collision community with access to hydrodynamic simulation software which is now accessible from within the primary …

Thermal modelling of ultrarelativistic heavy ion collisions conserving strangeness exactly
… missing] Thermal modelling of particle production in ultrarelativistic heavy ion collisions incorporating appropriate conservation principles with respect to the relevant quantum numbers, has been highly successful in determining chemical freeze-out conditions across a wide range of beam …

Early time dynamics & longitudinal structure of high-energy heavy-ion collisions
We investigate the out-of-equilibrium dynamics of heavy-ion collisions by performing real-time lattice simulations, accompanied by analytical considerations within the framework of the Color Glass Condensate (CGC) effective theory of QCD. The central aim of this work is to relax the assumption of …

Two Particle Correlations And The Ridge In Relativistic Heavy Ion Collisions
<p>Measurements at the Relativistic Heavy Ion Collider (RHIC) find an enhancement of two particle correlations in relativistic heavy ion collisions, not present in proton-proton collisions. Because the correlation structure is wide in relative pseudorapidity and narrow in relative azimuthal angle, …

Maxima in strangeness observed in heavy ion collisions using statistical models
Nucleus-Nucleus collisions enable the heating and compression of nuclei in order to probe matter under extreme temperature and energy density. With a resonance gas mode, of hadronic matter, Hagedorn came to the conclusion that on increasing the energy density, hadronic matter could exist above a …

Jet quenching in heavy-ion collisions at LHC with CMS detector
The collision of highly relativistic nuclei can produce a volume of high energy density which can be used to learn about the behavior of quantum chromodynamics (QCD) at extreme conditions, such as those of the universe at times before and during the formation of hadrons out of quarks and gluons. …

Nuclear Fragmentation Energy and Momentum Transfer Distributions in Relativistic Heavy-Ion Collisions
<p>An optical model description of energy and momentum transfer in relativistic heavy-ion collisions, based upon composite particle multiple scattering theory, is presented. Transverse and longitudinal momentum transfers to the projectile are shown to arise from the real and absorptive part of the …

Machine Learning for Exotic Particle Detection in Ultraperipheral Relativistic Heavy-Ion Collisions
… the field of particle physics is ultraperipheral collisions. Ultraperipheral collisions are collisions of relativistic nuclei in which the impact parameter is greater than the sum of the two radii; this leads to electromagnetic interactions rather than strong interactions. Standard searches for …
