Abstract

Quark interactions inside baryons depend on the spin states of the quarks. We investigated the contribution of the spin–spin interactions of quarks in comparison with other factors necessary for diquark formation in baryons, concluding that the effects of spin–spin interactions are correlated with the state of angular momentum excitation.
