Non-perturbative Renormalization Constants using Ward Identities
T. Bhattacharya, S. Chandrasekharan, R. Gupta +2
We extend the application of vector and axial Ward identities to calculate , and , coefficients that give the mass dependence of the renormalization constants of th…

Partial Restoration of Flavor Symmetry for Chiral Staggered Fermions
Weonjong Lee, Stephen Sharpe
At non-zero lattice spacing the flavor symmetry of staggered fermions is broken to a discrete subgroup. We show that in the chiral limit the flavor symmetry of the pion effective L…

Anomalous Chiral Symmetry Breaking above the QCD Phase Transition
Shailesh Chandrasekharan, Dong Chen, Norman Christ +3
We study the anomalous breaking of U_A(1) symmetry just above the QCD phase transition for zero and two flavors of quarks, using a staggered fermion, lattice discretization. The pr…
