Temperature Dependence of Heavy Quark Diffusion from (2+1)-flavor Lattice QCD
Dennis Bollweg, Jorge Luis Dasilva Golán, Olaf Kaczmarek +7
We present a lattice determination of the heavy-quark diffusion coefficient in (2+1)-flavor QCD with almost physical quark masses. The momentum and spatial diffusion coefficients a…

First-order phase transition in dynamical 3-flavor QCD at imaginary isospin
Gergely Endrodi, Guy D. Moore, Alessandro Sciarra
We revisit QCD with three mass-degenerate quark flavors at an imaginary isospin chemical potential set to 4 pi T/3. This choice corresponds to a special point in the parameter spac…

Finite T topological Susceptibility with heavy Quarks
Bruno Högl, Guy D. Moore
Axion cosmology needs the QCD topological susceptibility between 400 and 1100 MeV. In this range the bottom quark is inconvenient to include in lattice simulations, but not heavy e…
