Direct real photons are arguably the most versatile tools to study relativistic heavy ion
collisions. They are produced, by various mechanisms, during the entire space-time history …

We review the current state of research on electromagnetic probes in the context of heavy-
ion collisions. The focus is on thermal photons and dileptons which provide unique insights …

Abstract This White Paper presents an overview of the current status and future perspective
of QCD research, based on the community inputs and scientific conclusions from the 2022 …

Hot QCD physics studies the nuclear strong force under extreme temperature and densities.
Experimentally these conditions are achieved via high-energy collisions of heavy ions at the …

The emission of real photons from a momentum-anisotropic quark-gluon plasma (QGP) is
affected by both the collective flow of the radiating medium and the modification of the local …

We review direct photons in the phenomenology of nuclear collisions at relativistic energies.
Direct photons carry information about the space–time evolution of nuclear collisions …

The PHENIX Collaboration presents a systematic study of inclusive π 0 production from p+
p, p+ Al, p+ Au, d+ Au, and He 3+ Au collisions at s NN= 200 GeV. Measurements were …

We report on new measurements of elliptic flow (v 2) of electrons from heavy-flavor hadron
decays at mid-rapidity (| y|< 0.8) in Au+ Au collisions at s NN= 27 and 54.4 GeV from the …

The second Hot QCD Matter 2024 conference at IIT Mandi focused on various ongoing
topics in high-energy heavy-ion collisions, encompassing theoretical and experimental …

A phenomenological study of the isolated photon production in high energy pp and p A
collisions at RHIC and LHC energies is performed. Using the color dipole approach we …
