Charm hadrons above
Swagato Mukherjee, P. Petreczky, S. Sharma
From the analysis of the lattice data on fluctuations and correlations of charm we conclude that open charm meson and baryon-like excitations exist above the QCD crossover temperat…
The Polyakov loop at next-to-next-to leading order
Matthias Berwein, Nora Brambilla, Peter Petreczky +1
We calculate the next-to-next-to-leading correction to the expectation value of the Polyakov loop or equivalently to the free energy of a static charge. This correction is of order…
Conserved Charge Fluctuations from Lattice QCD and the Beam Energy Scan
F. Karsch, A. Bazavov, H. -T. Ding +11
We discuss the next-to-leading order Taylor expansion of ratios of cumulants of net-baryon number fluctuations. We focus on the relation between the skewness ratio, $S_Bσ_B = χ_3^B…
In-medium quarkonium properties from a lattice QCD based effective field theory
Seyong Kim, Peter Petreczky, Alexander Rothkopf
In order to understand the experimental data on heavy quarkonium production in heavy ion collisions at RHIC and LHC it is necessary (though not sufficient) to pinpoint the properti…
Polyakov loop renormalization with gradient flow
Peter Petreczky, Hans-Peter Schadler
We propose to use the gradient flow for the renormalization of Polyakov loops in various representations. We study Polyakov loops in 2+1 flavor QCD using the HISQ action and lattic…
Lattice NRQCD study of quarkonium at non-zero temperature
Seyong Kim, Peter Petreczky, Alexander Rothkopf
To study the in-medium modification of quarkonium properties, charmonium correlators at (MeV) are calculated using the NRQCD formalism on…
Charm Degrees of Freedom in Quark Gluon Plasma
Swagato Mukherjee, Peter Petreczky, Sayantan Sharma
Lattice QCD studies on fluctuations and correlations of charm quantum number have established that deconfinement of charm degrees of freedom sets in around the chiral crossover tem…
Renormalization of the Polyakov loop with gradient flow
P. Petreczky, H. -P. Schadler
We use the gradient flow for the renormalization of the Polyakov loop in various representations. Using 2+1 flavor QCD with highly improved staggered quarks and lattices with tempo…
The curvature of the freeze-out line in heavy ion collisions
A. Bazavov, H. -T. Ding, P. Hegde +10
We calculate the mean and variance of net-baryon number and net-electric charge distributions from Quantum Chromodynamics (QCD) using a next-to-leading order Taylor expansion in te…
Diagonal and off-diagonal quark number susceptibilities at high temperatures
H. -T. Ding, Swagato Mukherjee, H. Ohno +2
We present continuum extrapolated lattice QCD results for up to fourth-order diagonal and off-diagonal quark number susceptibilities in the high temperature region of 300-700 MeV.…
