Quenched Chiral Behavior of Hadrons with Overlap Fermions

OSTI ID:801741
We study the quenched chiral behavior of hadrons with the pseudoscalar mass as low as {approx} 280 MeV. We look for quenched chiral logs in the pion mass, determine the renormalized quark mass, and observe quenched artifacts in the a{sub 0} and N* propagators. The calculation is done on a quenched lattice of size 20{sup 4} and a = 0.148(2) fm using overlap fermions and an improved gauge action.
