In this report we review recent progress achieved in the understanding of heavy quarkonium
under extreme conditions from a theory perspective. Its focus lies both on quarkonium …

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 present a lattice-QCD calculation of the light-quark connected contribution to window
observables associated with the leading-order hadronic vacuum polarization contribution to …

We review results from lattice QCD calculations on the thermodynamics of strong-interaction
matter with emphasis on input these calculations can provide to the exploration of the phase …

We compute the electromagnetic fields generated in heavy-ion collisions by using the
HIJING model. Although after averaging over many events only the magnetic field …

The hot and dense matter generated in heavy-ion collisions may contain domains which are
not invariant under P and CP transformations. Moreover, heavy-ion collisions can generate …

I review the origin and properties of electromagnetic fields produced in heavy‐ion collisions.
The field strength immediately after a collision is proportional to the collision energy and …

In this article we discuss the properties of electromagnetic fields in heavy-ion collisions and
consequences for observables. We address quantitatively the issue of the magnetic field …

A new set of equations for relativistic viscous hydrodynamics that captures both weak-
coupling and strong-coupling physics to second order in gradients has been developed …

Spectral densities encode nonperturbative information that enters the calculation of a
plethora of physical observables in strongly coupled field theories. Phenomenological …
