Baryons of lower spin in partially quenched large-Nc QCD are studied with particular emphasis to interpolation between fully unquenched and fully quenched limits. In large Nc limit of partially quenched QCD, we calculate ∆m, the chiral one-loop correction to baryon masses. We find that leading order contribution to ∆m is independent of number of ghost quarks introduced. For finite Nc, ∆m does satisfy the Bernard–Golterman’s third theorem and has no infared quenching singularity except for fully… CONTINUE READING
