Abstract
We compute the light hadron mass spectrum in quenched lattice QCD at b eta = 6.0 using the Sheikholeslami-Wohlert fermionic action. The calcu lation is done for several choices of the coefficient c(sw), including c(sw) = 0 and the recently proposed optimal value c(sw) = 1.769. We f ind that the individual masses change by up to 30% under 0(a) improvem ent.
