The strong coupling constant: State of the art and the decade ahead
/ d'Enterria, D. (CERN) ; Kluth, S. (Munich, Max Planck Inst.) ; Zanderighi, G. (Munich, Max Planck Inst.) ; Ayala, C. (Tarapaca U.) ; Benitez-Rathgeb, M.A. (Vienna U.) ; Bluemlein, J.

Theoretical predictions for particle production cross sections and decays at colliders rely heavily on perturbative Quantum Chromodynamics (QCD) calculations, expressed as an expansion in powers of the strong coupling constant $\alpha_s$. The current $\mathcal{O}(1\%)$ uncertainty of the QCD coupling evaluated at the reference Z boson mass, $\alpha_s(m_Z) = 0.1179 \pm 0.0009$, is one of the limiting factors to more precisely describe multiple processes at current and future colliders.

FLAG Review 2021
/ Flavour Lattice Averaging Group (FLAG) Collaboration
We review lattice results related to pion, kaon, $D$-meson, $B$-meson, and nucleon physics with the aim of making them easily accessible to the nuclear and particle physics communities. More specifically, we report on the determination of the light-quark masses, the form factor $f_+(0)$ arising in the semileptonic $K \to \pi$ transition at zero momentum transfer, as well as the decay constant ratio $f_K/f_\pi$ and its consequences for the CKM matrix elements $V_{us}$ and $V_{ud}$.

Temperature dependence of $\eta/s$ of strongly interacting matter: effects of the equation of state and the parametric form of $(\eta/s)(T)$
/ Auvinen, Jussi (Belgrade, Inst. Phys.) ; Eskola, Kari J. (Jyvaskyla U. ; Helsinki Inst. of Phys.) ; Huovinen, Pasi (Belgrade, Inst. Phys. ; Wroclaw U.) ; Niemi, Harri (Jyvaskyla U. ; Helsinki Inst. of Phys.) ; Paatelainen, Risto (CERN) ; Petreczky, Peter (Brookhaven)
We investigate the temperature dependence of the shear viscosity to entropy density ratio $\eta/s$ using a piecewise linear parametrization. To determine the optimal values of the parameters and the associated uncertainties, we perform a global Bayesian model-to-data comparison on Au+Au collisions at $\sqrt{s_{NN}}=200$ GeV and Pb+Pb collisions at $2.76$ TeV and $5.02$ TeV, using a 2+1D hydrodynamical model with the EKRT initial state. [...]

$\alpha_s$(2019) discussions summary
/ Alekhin, Sergey (Hamburg U., Inst. Theor. Phys. II ; Serpukhov, IHEP) ; Barreiro, Fernando (U. Autonoma, Madrid (main)) ; Bethke, Siegfried (Munich, Max Planck Inst.) ; Brambilla, Nora (Munich, Tech.

A summary of the main points of discussion raised during the talks and their follow-up questions,as well as in the round table of the last day of the $α_s$ (2019) workshop, is presented. The discussions not only focused on particular issues affecting each one of the individual $α_s$ extractions, but also on the current PDG categorization of $α_s$ measurements and on the methods used to average them into a single $α_s$ ($m_Z$) value.

Temperature dependence of $\eta/s$: uncertainties from the equation of state
/ Auvinen, Jussi (Belgrade, Inst. Phys.) ; Eskola, Kari J. (Helsinki U. ; Helsinki Inst. of Phys.) ; Huovinen, Pasi (Wroclaw U.) ; Niemi, Harri (Helsinki U. ; Helsinki Inst. of Phys.) ; Paatelainen, Risto (CERN) ; Petreczky, Péter (Brookhaven)
We perform a global model-to-data comparison on Au+Au collisions at $\sqrt{s_{NN}}=200$ GeV and Pb+Pb collisions at $2.76$ TeV and $5.02$ TeV, using a 2+1D hydrodynamics model with the EKRT initial state and a shear viscosity over entropy density ratio $(\eta/s)(T)$ with a linear $T$ dependence. To quantify the amount of uncertainty due to the choice of the equation of state (EoS), we compare analysis results based on four different EoSs: the well known $s95p$ parametrisation, an updated parametrisation based on the same list of particles in hadron resonance gas, but using recent lattice results for the partonic part of the EoS, and two new parametrisations based on the Particle Data Group 2016 particle list and the recent lattice results.

/ Aarts, G. (Swansea U.) ; Aichelin, J. (SUBATECH, Nantes) ; Allton, C. (Swansea U.) ; Arnaldi, R. (INFN, Turin) ; Bass, S.A. (Duke U.) ; Bedda, C. (Utrecht U.) ; Brambilla, N. (Munich, Tech.

Open and hidden heavy-flavor physics in high-energy nuclear collisions are entering a new and exciting stage towards reaching a clearer understanding of the new experimental results with the possibility to link them directly to the advancement in lattice Quantum Chromo-dynamics (QCD). Recent results from experiments and theoretical developments regarding open and hidden heavy-flavor dynamics have been debated at the Lorentz Workshop "Tomography of the quark-gluon plasma with heavy quarks}, which was held in October 2016 in Leiden, the Netherlands [...]
