The FASTSUM collaboration has been carrying out simulations of N-f = 2 + 1 QCD at nonzero temperature in the fixed-scale approach using anisotropic lattices. Here we present the status of these studies, including recent results for electrical conductivity and charge diffusion, and heavy quarkonium (charm and beauty) physics.

Recent developments in heavy flavor probes in lattice QCD

Open and Hidden CharmMesons at Finite Temperaturefrom Anisotropic Lattice QCD

The quark-gluon plasma (QGP) is conjectured to have existed in the early stages of the Big Bang and it has been discovered in heavy ion collisions. The internal properties of the medium are not…

In-medium P-wave quarkonium from the complex lattice QCD potential

A bstractWe extend our lattice QCD potential based study [1] of the in-medium properties of heavy quark bound states to P-wave bottomonium and charmonium. Similar to the behavior found in the S-wave…

Bayesian study of relativistic open and hidden charm in anisotropic lattice QCD

We present the first combined study of correlators and spectral properties of charmonium and open-charm-mesons at finite temperature using a fully relativistic lattice QCD approach. The QCD medium is…

Nonperturbative SU(3) thermodynamics and the phase transition

Abstract.The SU(3) equations of state (P(T), s(T), I(T)) are calculated within the Field Correlator Method both in the confined and the deconfined phases. The basic dynamics in our approach is…

Heavy quarkonium in any channel in resummed hot QCD

We elaborate on the fact that quarkonium in hot QCD should not be thought of as a stationary bound state in a temperature-dependent real potential, but as a short-lived transient, with an…

Electrical conductivity of the quark-gluon plasma across the deconfinement transition.

A lattice calculation is presented for the electrical conductivity σ of the QCD plasma with 2+1 dynamical flavors at nonzero temperature and an increase of σ/T across the transition is found.

Spectral functions at small energies and the electrical conductivity in hot quenched lattice QCD.

It is shown that at finite temperature the most commonly used algorithm, employing Bryan's method, is inherently unstable at small energies and a modification is given that avoids this.

Bottomonium above deconfinement in lattice nonrelativistic QCD.

It is found that the Υ is insensitive to the temperature in this range, while the χb propagators show a crossover from the exponential decay characterizing the hadronic phase to a power-law behavior consistent with nearly free dynamics at T ≃ 2T(c).
