Masses of low-lying baryons in the ground states in a power-law potential model with pseudoscalar meson, one-gluon and centre-of-mass corrections

The masses of low-lying baryons in the ground states are calculated in a re lativistic potential model of independent quarks taking into account pertur batively the contribution of the quark-gluon coupling due to one-gluon exch ange along with that of pseudoscalar meson exchange interaction and that of centre-of-mass motion. The effective potential representing phenomenologic ally the non-perturbative,gluon interactions, including the gluon self-coup lings, is chosen with equally mixed scalar and vector parts in a non-Coulom bic power-law form. The physical masses of the ground state baryons thus ob tained with the strong coupling constant alpha (c) = 0.165 agree reasonably well with the corresponding experimental values.
