Abstract

We study the possible baryon-number violating effects induced by the monopoles that are formed due to the spontaneous breakdown of the Pati-Salam [SU(2)L×SU(2)R×SU(4)]. This effect is due to the weak 't Hooft anomaly. Although the baryon-number violating condensates involving only the first and the second generation fermions are suppressed by powers of mixing angles, we show that all the relevant mixing angles may be large, while still being consistent with the smallness of the Kobayashi-Maskawa mixing angles. Hence the baryon-number violating effects caused by such monopoles need not be suppressed.
