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 …

▪ Abstract We review lattice QCD investigations at high temperature. After a short
introduction to thermal QCD on the lattice, we report on the present understanding of the …

Recent SU (3) gauge field lattice data for the equation of state are interpreted by a
quasiparticle model with effective thermal gluon masses. The model is motivated by lowest …

We study to what extent the three-dimensional SU (N)+ adjoint Higgs theory can be used as
an effective theory for finite-temperature SU (N) gauge theory, with N= 2, 3. The parameters …

Heavy quark potentials are investigated at high temperatures. The temperature range
covered by the analysis extends from T values just below the deconfinement temperature up …

The current understanding of finite-temperature phase transitions in QCD is reviewed. A
critical discussion of refined phase-transition criteria in numerical lattice simulations and of …

We study the MSSM finite temperature electroweak phase transition with lattice Monte Carlo
simulations, for a large Higgs mass (mH≈ 95 GeV) and light stop masses (mt ̃ R∼ 150–160 …

We study correlation functions of spatially separated static quark-antiquark pairs in (2+ 1)-
flavor QCD in order to investigate onset and nature of color screening at high temperatures …

We use a perturbatively derived effective field theory and three-dimensional lattice
simulations to determine the longest static correlation lengths in the deconfined QCD …

The strict coupling constant expansion for the free energy of hot QCD plasma shows bad
convergence at all reasonable temperatures, and does not agree well with its 4D lattice …
