Abstract
Vector SO(3) gauged O(4) sigma models on R(3) are presented. The topol ogical charge supplying the lower bound on the energy and rendering th e soliton stable coincides with the baryon number of the Skyrmion. The se solitons have vanishing magnetic monopole flux. To exhibit the exis tence of such solitons, the equations of motion of one of these models are integrated numerically. The structure of the conserved baryon cur rent is briefly discussed.
