Abstract Quark–Gluon Plasma (QGP), a QCD state of matter created in ultra-relativistic
heavy-ion collisions, has remarkable properties including, for example, a low shear viscosity …

We review the current status of jet measurements in heavy-ion collisions at the Large
Hadron Collider (LHC) and the Relativistic Heavy Ion Collider (RHIC). We discuss how the …

An improved measurement of the decay B s 0→ μ+ μ-and searches for the decays B 0→ μ+
μ-and B s 0→ μ+ μ-γ are performed at the LHCb experiment using data collected in proton …

Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers” …

We introduce a model for heavy ion collisions named trajectum, which includes an
expanded initial stage with a variable free streaming velocity v fs and a hydrodynamic stage …

High-energy cosmic rays are observed indirectly by detecting the extensive air showers
initiated in Earth's atmosphere. The interpretation of these observations relies on accurate …

The understanding of heavy ion collisions and its quark-gluon plasma (QGP) formation
requires a complicated interplay of rich physics in a wealth of experimental data. In this work …

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 …

Heavy ion collisions quickly form a droplet of quark–gluon plasma (QGP) with a remarkably
small viscosity. We give an accessible introduction to how to study this smallest and hottest …

We simulate the space-time dynamics of high-energy collisions based on a microscopic
kinetic description in the conformal relaxation time approximation, in order to determine the …
