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 ...

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 ...

Confinement of Fermions in Tachyon Matter at Finite Temperature

open access: yesAdvances in High Energy Physics, 2021
We study a phenomenological model that mimics the characteristics of QCD theory at finite temperature. The model involves fermions coupled with a modified Abelian gauge field in a tachyon matter.

Quark–gluon plasma signals

open access: yesEuropean Journal of Physics, 2003
We study the evolution of matter produced after the collision of two heavy nuclei at high energy. The matter produced may pass from the hadron phase into a new state of matter called quark–gluon plasma (QGP). The aim of this paper is to discuss how a new state of matter can be observed.

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.

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

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 ...

The flavours of the quark–gluon plasma [PDF]

open access: yesJournal of Physics G: Nuclear and Particle Physics, 2009
Quarks of other flavours than up and down, i.e. $s$, $c$, and $b$ quarks, have been long recognized as effective probes of the structure of hot QCD matter. In this talk, I review some of the motivations for their investigation and discuss the salient results obtained so far, with a focus on the results from the Relativistic Heavy Ion Collider (RHIC ...

Measurement of the top quark charge in pp collisions at s√=7 TeV with the ATLAS detector [PDF]

open access: yes, 2011
A measurement of the top quark electric charge is carried out in the ATLAS experiment at the Large Hadron Collider using 2.05 fb−1 of data at a centre-of-mass energy of 7 TeV. In units of the elementary electric charge, the top quark charge is determined

Probing the gluon plasma with charm balance functions

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
Recent theoretical explanations for how hydrodynamic-like flow can build up quickly in small collision systems (hydrodynamization) has led to a microscopic picture of flow building up in a gluon-dominated phase before chemical equilibrium between quarks ...
