We study the quenched chiral behavior of hadrons with the pseudoscalar mass as low as ≈ 280 MeV. We look for quenched chiral logs in the pion mass, determine the renormalized quark mass, and observe quenched artifacts win the a0 and N* propagators. The calculation is done on a quenched lattice of size 204 and a = 0.148(2) fm using overlap fermions and an improved gauge action.
