The Quest for the Quark‐Gluon Plasma From the Perspective of Dynamical Models of Relativistic Heavy‐Ion Collisions

open access: yesAstronomische 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.

Quark number scaling of hadronic pT spectra and constituent quark degree of freedom in p–Pb collisions at sNN=5.02 TeV

open access: yesPhysics Letters B, 2017
We show that the experimental data of transverse momentum (pT) spectra of identified hadrons released recently by ALICE collaboration for p–Pb collisions at sNN=5.02 TeV exhibit a distinct universal behavior — the quark number scaling.

Adiabatic hydrodynamization in rapidly-expanding quark–gluon plasma

open access: yesPhysics Letters B, 2021
We propose a new scenario characterizing the transition of the quark–gluon plasma (QGP) produced in heavy-ion collisions from a highly non-equilibrium state at early times toward a fluid described by hydrodynamics at late times.

Jet quenching and broadening: the transport coefficient $\hat{q}$ in an anisotropic plasma

open access: yes, 2008
The jet quenching parameter $\hat{q}$ is analyzed for a quark jet propagating in an anisotropic plasma. The momentum anisotropy is calculated at high temperature of the underlying quark-gluon plasma.

“QGP Signatures” revisited

open access: yesEuropean Physical Journal C: Particles and Fields
We revisit the graphic table of QCD signatures in our 1996 Annual Reviews article “The Search for the Quark–Gluon Plasma” and assess the progress that has been made since its publication towards providing quantitative evidence for the formation of a ...

Viscous QCD medium effects on the bottom quark transport coefficients

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
The bottom quark transport coefficients, i.e., drag and diffusion coefficients, have been studied for the collisional and soft gluon radiative processes within the viscous QCD medium.

Thermal Charm Production in Quark-Gluon Plasma at LHC

open access: yes, 2008
Charm production from the quark-gluon plasma created in the midrapidity of central heavy ion collisions at the Large Hadron Collider (LHC) is studied in the next-to-leading order in QCD.

A New Phase of Matter: Quark-Gluon Plasma Beyond the Hagedorn Critical Temperature [PDF]

open access: yes, 2015
I retrace the developments from Hagedorn's concept of a limiting temperature for hadronic matter to the discovery and characterization of the quark-gluon plasma as a new state of matter.

Partition Functions and Mass Action Constants of Plasmas of Light Elements at Higher Temperatures

open access: yesContributions to Plasma Physics, Volume 65, Issue 7, August 2025.
ABSTRACT We first analyze the relations between the work of Planck and Klimontovich and show that Klimontovich's kinetic theory of non‐ideal plasmas confirms Planck's partition function for the hydrogen plasma. We discuss and check the Planck‐Brillouin‐Larkin (PBL) expressions for Hydrogen with PIMC calculations and derive new partition functions and ...

Drag induced radiation and multi-stage effects in heavy-flavor energy loss

open access: yesPhysics Letters B, 2019
It is argued that heavy-quarks traversing a Quark Gluon Plasma, undergo a multi-stage modification process, similar to the case of light flavors. Such an approach is applied to heavy-quark energy loss, which includes a rare-scattering, multiple emission ...
