Abstract

We compute the light hadron mass spectrum in quenched lattice QCD at β= 6.0 using the Sheikholeslami-Wohlert fermionic action. The calculation 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 find that the individual masses change by up to 30% under O(a) improvement. The spectrum calculation suggests c_SW ≈ 1.4 for the optimal value of the coefficient.
