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.

Measurement of the four-lepton invariant mass spectrum in 13 TeV proton-proton collisions with the ATLAS detector

open access: yesJournal of High Energy Physics, 2019
A measurement of the four-lepton invariant mass spectrum is made with the ATLAS detector, using an integrated luminosity of 36.1 fb−1 of proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV delivered by the Large Hadron Collider.

Search for new phenomena in final states with large jet multiplicities and missing transverse momentum using s $$ \sqrt{s} $$ = 13 TeV proton-proton collisions recorded by ATLAS in Run 2 of the LHC

open access: yesJournal of High Energy Physics, 2020
Results of a search for new particles decaying into eight or more jets and moderate missing transverse momentum are presented. The analysis uses 139 fb −1 of proton-proton collision data at s $$ \sqrt{s} $$ = 13 TeV collected by the ATLAS experiment at ...

QCD: Challenges for the Future [PDF]

open access: yes, 1996
Despite many experimental verifications of the correctness of our basic understanding of QCD, there remain numerous open questions in strong interaction physics and we focus on the role of future colliders in addressing these questions.

Two Micron‐Size Dark Dimensions

open access: yesFortschritte der Physik, Volume 73, Issue 8, August 2025.
Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

Basics of QCD Perturbation Theory: TASI 2000

open access: yes, 2000
This is an introduction to the use of QCD perturbation theory, emphasizing generic features of the theory that enable one to separate short-time and long-time effects. I also cover some important classes of applications: electron-positron annihilation to

Search for supersymmetry in final states with missing transverse momentum and multiple b-jets in proton-proton collisions at s=13 $$ \sqrt{s}=13 $$ TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2018
A search for supersymmetry involving the pair production of gluinos decaying via third-generation squarks into the lightest neutralino χ˜10 $$ \left({\tilde{\chi}}_1^0\right) $$ is reported.

Centrality dependence of J/ψ and ψ(2S) production and nuclear modification in p-Pb collisions at s NN $$ \sqrt{s_{\mathrm{NN}}} $$ = 8.16 TeV

open access: yesJournal of High Energy Physics, 2021
The inclusive production of the J/ψ and ψ(2S) charmonium states is studied as a function of centrality in p-Pb collisions at a centre-of-mass energy per nucleon pair s NN $$ \sqrt{s_{\mathrm{NN}}} $$ = 8.16 TeV at the LHC. The measurement is performed in
