Hesse for FAIR) ; Bruno, Mattia (Milan Bicocca U. ; INFN, Milan Bicocca) ; Caselle, Michele (Turin U.) et al.
Phase transitions in a non-perturbative regime can be studied by ab initio Lattice Field Theory methods. The status and future research directions for LFT investigations of Quantum Chromo-Dynamics under extreme conditions are reviewed, including properties of hadrons and of the hypothesized QCD axion as inferred from QCD topology in different phases.

This report summarizes the presentations and discussions during the Rapid Reaction Task Force "Dynamics of critical fluctuations: Theory -- phenomenology -- heavy-ion collisions", which was organized by the ExtreMe Matter Institute EMMI and held at GSI, Darmstadt, Germany in April 2019. We address the current understanding of the dynamics of critical fluctuations in QCD and their measurement in heavy-ion collision experiments. [...]

Non-perturbative thermal flows and resummations / Litim, Daniel F. (Southampton U. ; CERN) ; Pawlowski, Jan M. (Heidelberg U.)
We construct a functional renormalisation group for thermal fluctuations. Thermal resummations are naturally built in, and the infrared problem of thermal fluctuations is well under control. [...]

Infrared QCD and the Renormalisation Group / Litim, Daniel F. (CERN ; Southampton U.) ; Pawlowski, Jan M. (Erlangen - Nuremberg U., Theorie III) ; Nedelko, Sergei (Erlangen - Nuremberg U., Theorie III) ; von Smekal, Lorenz (Erlangen - Nuremberg U., Theorie III)
We study the infrared regime of QCD by means of a Wilsonian renormalisation group. We explain how, in general, the infrared structure of Green functions is deduced in this approach. [...]

Wilsonian flows and background fields / Litim, Daniel F. (CERN) ; Pawlowski, Jan M. (Erlangen - Nuremberg U.)
We study exact renormalisation group flows for background field dependent regularisations. It is shown that proper-time flows are approximations to exact background field flows for a specific class of regulators. [...]

Renormalisation group flows for gauge theories in axial gauges / Litim, Daniel F. (CERN) ; Pawlowski, Jan M. (Erlangen - Nuremberg U.)
Gauge theories in axial gauges are studied using Exact Renormalisation Group flows. We introduce a background field in the infrared regulator, but not in the gauge fixing, in contrast to the usual background field gauge. [...]

Completeness and consistency of renormalisation group flows / Litim, Daniel F. (CERN) ; Pawlowski, Jan M. (Erlangen - Nuremberg U., Theorie III)
We study different renormalisation group flows for scale dependent effective actions, including exact and proper-time renormalisation group flows. These flows have a simple one loop structure. [...]

Perturbation theory and renormalisation group equations / Litim, Daniel F. (CERN) ; Pawlowski, Jan M. (Erlangen - Nuremberg U., Theorie III)
We discuss the perturbative expansion of several one-loop improved renormalisation group equations. It is shown that in general the integrated renormalisation group flows fail to reproduce perturbation theory beyond one loop..

Predictive power of renormalisation group flows : a comparison / Litim, Daniel F. (CERN) ; Pawlowski, Jan M. (Erlangen - Nuremberg U.)
We study a proper-time renormalisation group, which is based on an operator cut-off regularisation of the one-loop effective action. The predictive power of this approach is constrained because the flow is not an exact one. [...]
