Description

We calculate the low-lying meson and baryon masses in quenched QCD for three different couplings: β=5.4, β=5.7 and β=5.9. The sizes of our lattices are 83x16 (β=5.4) and 103x16 (β=5.7 and β=5.9). We use Kogut-Susskind fermions because they possess an explicit continuous chiral symmetry which we have shown to be broken spontaneously. We find that the meson and baryon masses and the resulting quark mass conform to the continuum renormalization group behaviour to a statistically significant degree. Furthermore, our results are in good agreement with the experimental masses and low-energy parameters for Λsub(mom)approx.=200 MeV. This is also roughly the scale parameter one obtains from a variety of other quantities. (orig.)
