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 …

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 …

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, …

Centrality dependence of two-particle correlations in relativistic heavy ion collisions
… centrality dependence of two-particle correlations in Au+Au collisions at ... 200GeV are presented. A particular focus is devoted to investigating any anomalous behavior in the centrality dependence of correlation functions, as previous results suggest existence of such tendencies around Npart …

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 …

Canonical strangeness conservation in the hadron gas model of relativistic heavy ion collisions
… with canonical (exact) strangeness conservation involving all strange resonances, and grand canonical conservation of charge and baryon number. It is shown that the data are well described by an equilibrium hadron gas. Other explanations of these data are reviewed.

Search for clustering of strange quarks in relativistic heavy ion collisions at the LHC
Heavy ion collisions at the LHC provide a tool to study the phase transition from hadronic matter to a deconfined phase of quarks and gluons. We investigated whether flavor hierarchy in the QCD transition crossover region could lead to clustering of strangeness. The idea was supported by the …

Hadronic gas description of relativistic heavy ion collisions incorporating exact conservation of quantum numbers
The hadron production (especially kaon production) and the hadronic ratios (especially K/π) in heavy ion collisions are studied assuming that particles are produced in a hadron gas at both thermal and chemical equilibrium. The final state in relativistic ion collision is described by a hadronic gas …

Jet study in ultra-relativistic heavy-ion collisions with the ALICE detectors at the LHC
… thesis presents first results on jet reconstruction in simulated Pb+Pb collisions using the ALICE detectors and a UAl-based cone jet finding algorithm which has been modified and optimised to reconstruct high-PT jets on an event-by-event basis. Optimisation of the algorithm parameters and methods …

Energy and centrality dependence of mid-rapidity charged particle multiplicity in relativistic heavy-ion collisions

Heavy quark interaction in Hot QCD matter: open charm and bottom production in relativistic Heavy-Ion Collisions
