2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/197022We 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 $a_0$ and $N^*$ propagators. The calculation is done on a quenched lattice of size $20^4$ and $a = 0.148(2)$ fm using overlap fermions and an improved gauge action.Lattice2001(spectrum), 3 pages, 4 figures (uses rotate.sty)High Energy Physics - Latticetext
