Highly improved staggered quarks on anisotropic lattices
Alexei Bazavov, Yannis Trimis, Johannes Heinrich Weber
We present a study of tuning of the anisotropic highly improved staggered quark (aHISQ) action on pure gauge ensembles with the renormalized anisotropy ranging from 1 to 8. We disc…
Charmonium properties at high temperatures from lattice QCD
Rasmus Normann Larsen, Peter Petreczky, Jorge Luis Dasilva Golan +1
We study charmonium properties at non-zero temperature in the temperature range 153 MeV 305 MeV using lattice QCD. We use HISQ action for dynamical quarks and Wilson clover a…
Strong coupling constant from the 1-loop improved static energy
Viljami Leino, Alexei Bazavov, Nora Brambilla +8
The static energy is an excellent observable for extracting the strong coupling on the lattice. For short distances, the static energy can be calculated both on the lattice…
Fluctuation-Dissipation Relation for Hard Partons in a Gluonic Plasma
Amit Kumar, Abhijit Majumder, Ismail Soudi +1
We derive a fluctuation dissipation relation connecting the drag and diffusion jet transport coefficients for an energetic light quark traversing a non-perturbative thermalized glu…
Scale Setting and Strong Coupling Determination in the Gradient Flow Scheme for 2+1 Flavor Lattice QCD
Rasmus Larsen, Swagato Mukherjee, Peter Petreczky +2
We report on the determination of the gradient flow scales in QCD using highly improved staggered quark (HISQ) ensembles generated by the HotQCD Collaboration for bare ga…
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…
