The ALICE experiment was proposed in 1993, to study strongly-interacting matter at extreme
energy densities and temperatures. This proposal entailed a comprehensive investigation of …

We review the present status of the search for a phase transition and critical point as well as
anomalous transport phenomena in Quantum Chromodynamics (QCD), with an emphasis …

Abstract The Beam Energy Scan Theory (BEST) Collaboration was formed with the goal of
providing a theoretical framework for analyzing data from the Beam Energy Scan (BES) …

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 …

The Breit-Wheeler process which produces matter and antimatter from photon collisions is
experimentally investigated through the observation of 6085 exclusive electron-positron …

Ultraperipheral collisions (UPCs) of heavy ions and protons are the energy frontier for
electromagnetic interactions. Both photonuclear and two-photon collisions are studied at …

The topological structure of vacuum is the cornerstone of non-Abelian gauge theories
describing strong and electroweak interactions within the standard model of particle physics …

We investigate the impact of soft gluon resummation on the azimuthal angle correlation
between the total and relative momenta of two energetic final-state particles (jets). We show …

The future opportunities for high-density QCD studies with ion and proton beams at the LHC
are presented. Four major scientific goals are identified: the characterisation of the …

The first measurement of the dependence of γ γ→ μ+ μ− production on the multiplicity of
neutrons emitted very close to the beam direction in ultraperipheral heavy ion collisions is …
