Thermodynamics of strong interaction matter from lattice QCD and the hadron resonance gas model
Frithjof Karsch
We compare recent lattice QCD calculations of higher order cumulants of net-strangeness fluctuations with hadron resonance gas (HRG) model calculations. Up to the QCD transition te…
Meson screening masses at finite temperature with Highly Improved Staggered Quarks
Y. Maezawa, A. Bazavov, F. Karsch +2
We report on the first study of the screening properties of the mesonic excitations with strange () and charm () quarks, specifically the ground states of the pseudo-scalar a…
Chiral phase transition of =2+1 QCD with the HISQ action
H. -T. Ding, A. Bazavov, F. Karsch +3
We present studies of universal properties of the chiral phase transition in =2+1 QCD based on the simulations using Highly Improved Staggered fermions on lattices with tempor…
Investigation of the in high temperature QCD on the lattice
Sayantan Sharma, Viktor Dick, Frithjof Karsch +2
In this project we study the effect of the anomaly for (2+1)-flavour QCD at high temperature. We apply the overlap operator as a tool to probe the topological properties o…
The QCD chiral transition, $\ua$ symmetry and the Dirac spectrum using domain wall fermions
Michael I. Buchoff, Michael Cheng, Norman H. Christ +11
We report on a study of the finite-temperature QCD transition region for temperatures between 139 and 196 MeV, with a pion mass of 200 MeV and two space-time volumes: …
Quark number susceptibilities at high temperatures
A. Bazavov, H. -T. Ding, P. Hegde +6
We calculate second and fourth order quark number susceptibilities for 2+1 flavor QCD in the high temperature region. In our study we use two improved staggered fermion formulation…
