QCD Chiral Crossover Line from Lee-Yang Edge Singularities
Heng-Tong Ding, Swagato Mukherjee, Peter Petreczky +1
We propose a universality-based reconstruction of the QCD chiral crossover line from Lee-Yang edge singularities in the complex baryon chemical potential plane. The framework maps…
Proton isovector helicity PDF at NNLO and the twist-3 moment from lattice QCD at physical quark masses
Xiang Gao, Andrew D. Hanlon, Swagato Mukherjee +5
We present a lattice quantum chromodynamics calculation of the -dependent isovector quark helicity parton distribution function (PDF) of the proton in the large momentum effecti…
Spatial String Tension at High Temperatures and Quantitative Tests of Dimensionally Reduced Effective Theories
Vishal Rao, Peter Petreczky, Prasad Hegde
We calculate the spatial string tension in 2+1 flavour QCD in dimensions within a temperature range of using spatial Wilson loo…
Bottomonium Properties in QGP from a Lattice-QCD Informed T-Matrix Approach
Zhanduo Tang, Swagato Mukherjee, Peter Petreczky +1
Recent lattice quantum chromodynamics (lQCD) computations of bottomonium correlation functions with extended sources provide new insights into heavy-quark dynamics at distance scal…
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…
