Pion Decay Constant, and Chiral Log from Overlap Fermions
S. J. Dong, T. Draper, I. Horvath +2
We report our calculation of the pion decay constant , the axial renormalization constant , and the quenched chiral logarithms from the overlap fermions. The calculation…
Quenched Chiral Behavior of Hadrons with Overlap Fermions
Shao-Jing Dong, Terrence Draper, Ivan Horvath +2
We study the quenched chiral behavior of hadrons with the pseudoscalar mass as low as MeV. We look for quenched chiral logs in the pion mass, determine the renormaliz…
Topological Charge Fluctuations and Low-Lying Dirac Eigenmodes
S. J. Dong, T. Draper, I. Horvath +5
We discuss the utility of low-lying Dirac eigenmodes for studying the nature of topological charge fluctuations in QCD. The implications of previous results using the local chirali…
Evidence Against Instanton Dominance of Topological Charge Fluctuations in QCD
Ivan Horvath, Nathan Isgur, John McCune +1
The low-lying eigenmodes of the Dirac operator associated with typical gauge field configurations in QCD encode, among other low-energy properties, the physics behind the solution…
