摘要: The pseudoparticle solutions of non-Abelian gauge theories can generate a mass for fermions coupled to the fields. SU(N) x chiral symmetry model with N species massless is spontaneously broken by this effect, and N/sup 2/-1 Goldstone bosons are consequently formed as bound states fermion-antifermion pairs. We demonstrate these facts explicitly in models one or two fermions. mechanism which acquire such that symmetries P T conserved even presence pseudoparticles.
