Correlated Dirac Eigenvalues and Axial Anomaly in Chiral Symmetric QCD
Heng-Tong Ding, Sheng-Tai Li, Swagato Mukherjee +3
We investigate the Dirac eigenvalue spectrum () to study the microscopic origin of axial anomaly in high temperature phase of QCD. We propose novel relations between the…
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…
