Abstract
Physical quark-number charges of dyons are determined, via a formula w hich generalizes that of Witten for the electric charge, in N = 2 supe rsymmetric theories with SU(2) x U(1)(Nf) gauge group. The quark numbe rs of the massless monopole at a nondegenerate singularity of the spac e of vacua turn out to vanish in all cases. A puzzle related to CP inv ariant cases is solved. Generalization of our results to SU(N-c) x U(1 )(Nf) gauge theories is straightforward.
