Abstract
We study the hadronic mass spectrum in quenched lattice QCD. We present the results of numerical simulations done at β = 5.7 and β = 6.0. B and A1 meson masses get much closer to the physical values at β = 6.0, and so do the baryonic splittings. The mass ratio mp mp in the chiral limit tends to be from 10 to 20% higher than the experimental value. We estimate the nucleon σ term from the proton mass slope. © 1988.File in questo prodotto:
