Extraction of Effective Parameters From Transverse Momentum Spectra of Heavy Quarkonia in Proton–Proton Collisions at the LHC

open access: yesAdvances in High Energy Physics, Volume 2026, Issue 1, 2026.
The effective string tension (κ) in the Schwinger mechanism and the effective temperature (T) in Bose–Einstein statistics are extracted from the transverse momentum (pT) spectra of heavy quarkonia produced in proton‐proton (p + p) collisions at the Large Hadron Collider (LHC).

Quarkonium states in an anisotropic quark-gluon plasma [PDF]

open access: yes, 2009
In this work we study the properties of quarkonium states in a quark-gluon plasma which, due to expansion and non-zero viscosity, exhibits a local anisotropy in momentum space.

“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 ...

Radiation Transport Through the Martian Atmosphere as a Function of the Zenith Angle

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract The topographic influence of the radiation environment on the Martian surface radiation is crucial for future human exploration. Topographic maps help assess radiation flux variations, aiding in hazard evaluation. Creating a global radiation map requires accounting for seasonally varying atmospheric density, heliospheric modulation, and ...

Kollektive Phänomene im Nichtgleichgewichts-Quark-Gluon-Plasma [PDF]

open access: yes, 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,

The effect of weak magnetic photon emission from quark-gluon plasma

open access: yesPhysics Letters B
We propose a novel effect that accounts for the photon emission from a quark-gluon plasma in the presence of a weak external magnetic field. Although the weak magnetic photon emission from quark-gluon plasma only leads to a small correction to the photon

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.

Electrical conductivity of the quark-gluon plasma from the low energy limit of photon and dilepton spectra

open access: yesPhysics Letters B, 2023
Fluid dynamic considerations are used to determine the electric current spectral density in the regime of small energies and momenta. The spectral density in this regime is parameterized by the electric conductivity, the charge susceptibility, and the ...
