We review the progress achieved in extracting the properties of hot and dense matter from
relativistic heavy ion collisions at the relativistic heavy ion collider (RHIC) at Brookhaven …

We discuss the basic ideas of relativistic transport models used for the interpretation and
description of experimental data from heavy-ion collisions at high collision energies. We …

A search for sub-GeV dark matter production mediated by a new vector boson A′, called a
dark photon, is performed by the NA64 experiment in missing energy events from 100 GeV …

Thermal dark matter models with particle χ masses below the electroweak scale can provide
an explanation for the observed relic dark matter density. This would imply the existence of a …

Direct photon production at mid-rapidity in Pb–Pb collisions at s NN= 2.76 TeV was studied
in the transverse momentum range 0.9< p T< 14 GeV/c. Photons were detected with the …

A linearized Boltzmann transport (LBT) model coupled with hydrodynamical background is
established to describe the evolution of jet shower partons and medium excitations in high …

This work studies the production of direct photons in relativistic nuclear collisions, along with
the production of hadrons. Radiation from the very first instants to the final moments of the …

The improved results on a direct search for a new X (16.7 MeV) boson that could explain the
anomalous excess of e+ e-pairs observed in the decays of the excited Be* 8 nuclei …

The production of ground-state and excited bottomonia in ultrarelativistic heavy-ion
collisions is investigated within a kinetic-rate equation approach including regeneration. We …

We propose an inclusive search for dark photons A′ at the LHCb experiment based on
both prompt and displaced dimuon resonances. Because the couplings of the dark photon …
