Bottomonia screening masses from flavor QCD
Peter Petreczky, Sayantan Sharma, Johannes Heinrich Weber
The sequential melting of the bottomonium states is one of the important signals for the existence of a quark gluon plasma. The study of bottomonia spectral functions on the lattic…
Chromo-electric screening length in 2+1 flavor QCD
Peter Petreczky, Sebastian Steinbeißer, Johannes Heinrich Weber
We study Polyakov loop as well as correlators of real and imaginary parts of the Polyakov loop in 2+1 flavor QCD at finite temperature. We use hypercubic (HYP) smearing to improve…
Lattice QCD Determination of the Bjorken- Dependence of Parton Distribution Functions at Next-to-next-to-leading Order
Xiang Gao, Andrew D. Hanlon, Swagato Mukherjee +4
We report the first lattice QCD calculation of pion valence quark distribution with next-to-next-to-leading order perturbative matching correction, which is done using two fine lat…
The complex potential from 2+1 flavor QCD using HTL inspired approach
Dibyendu Bala, Olaf Kaczmarek, Rasmus Larsen +5
We have studied finite temperature complex static quark-antiquark potentials for 2+1 flavor QCD using highly improved staggered action with physical strange quark masses and light…
Correlated Dirac eigenvalues around the transition temperature on lattices
Heng-Tong Ding, Wei-Ping Huang, Min Lin +3
We investigate the criticality of chiral phase transition manifested in the first and second order derivatives of Dirac eigenvalue spectrum with respect to light quark mass in (2+1…
In-medium static quark potential from spectral functions on realistic HISQ ensembles

Julian Mayer-Steudte, Nora Brambilla, Viljami Leino +1
The heavy quark diffusion coefficient is encoded in the spectral functions of the chromoelectric and the chromomagnetic correlators that are calculable on the lattice. We study the…

Sebastian Steinbeißer, Nora Brambilla, Rafael L. Delgado +5
We report on the status of the analysis of the static energy in -flavor QCD. The static energy is obtained by measuring Wilson line correlators in Coulomb gauge using the HI…

Dibyendu Bala, Olaf Kaczmarek, Rasmus Larsen +5
We study the interactions of a static quark antiquark pair at non-zero temperature using realistic 2+1 flavor lattice QCD calculations. The study consists of two parts: the first i…
