Unified Description of Ground State Mesons and Baryons in a Potential Model

摘要

Ground state masses are calculated using the Cornell potential for all mesons and baryons and assuming V/sub qq/=1/2V/sub qq-bar/ quark-quark potential. A good fit of spin-spin splittings for mesons and baryons is obtained with the QCD coupling constant alpha /sub S/(Q/sup 2/). The resulting masses agree with the experimental ones within approx. 20 MeV for both mesons and baryons. 13 refs. (Atomindex citation 19:010814)
