Kollektive Phänomene im Nichtgleichgewichts-Quark-Gluon-Plasma [PDF]
, 2008 In this work we study the non-equilibrium dynamics of a quark-gluon plasma, as created in heavy-ion collisions. We investigate how big of a role plasma instabilities can play in the isotropization and equilibration of a quark-gluon plasma. In particular,

EPJ Featured Talk: First direct measurement of radial flow in heavy-ion collisions with ALICE [PDF]
EPJ Web of ConferencesThis work presents measurements of the transverse-momentum-dependent observable v0(pT) as a novel probe of radial expansion dynamics in Pb-Pb collisions at √sNN = 5.02 TeV with the ALICE detector. Results are reported for inclusive charged hadrons, pions,

Charm degrees of freedom in the quark gluon plasma [PDF]
, 2015 Lattice QCD studies on fluctuations and correlations of charm quantum number have established that deconfinement of charm degrees of freedom sets in around the chiral crossover temperature, ${T}_{c}$; i.e., charm degrees of freedom carrying fractional ...

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.Abstract The production, attenuation, and absorption of secondary cosmic rays (SCR) are influenced by atmospheric parameters such as air pressure and temperature. To reliably correlate SCR flux measurements with atmospheric ionization driven by energetic particle precipitation, these dependencies must be quantified.

Quark and Gluon Form Factors at Three Loops in Perturbative QCD [PDF]
, 2009 We compute the quark and gluon form factors at up to three-loop order within massless perturbative Quantum Chromodynamics by studying the photon-quark-anti-quark vertex and the effective vertex of a Higgs boson and two gluons.

Event-by-event picture for the medium-induced jet evolution
EPJ Web of Conferences, 2017 We discuss the evolution of an energetic jet which propagates through a dense quark-gluon plasma and radiates gluons due to its interactions with the medium. Within perturbative QCD, this evolution can be described as a stochastic branching process, that

Nucleon quark distribution functions from the Dyson–Schwinger equations
Physics Letters B, 2018 We present results for the nucleon's leading-twist spin-independent valence parton distribution functions obtained from a theoretical framework based on the Dyson–Schwinger equations (DSEs) of QCD that previously gave an excellent description of nucleon ...

Astronomische Nachrichten, Volume 346, Issue 7-8, September 2025.ABSTRACT The physics of heavy‐ion collisions is one of the most exciting and challenging directions of science for the last four decades. On the theoretical side one deals with a non‐abelian field theory, while on the experimental side today's largest accelerators are needed to enable these studies.

The phase transition to the quark-gluon plasma and its effect on hydrodynamic flow [PDF]
, 2005 It is shown that in ideal relativistic hydrodynamics a phase transition from hadron to quark and gluon degrees of freedom in the nuclear matter equation of state leads to a minimum in the excitation function of the transverse collective ...

Dynamical correlations across momentum scales in the quark–gluon plasma
Physics Letters BExperimental probes of the Quark-Gluon Plasma (QGP) generated in heavy–ion collisions span a broad range in momentum scale: low transverse momentum (low p T ) measurements probe collective dynamics, while high p T measurements probe the response to QGP ...
