ON THE HIGGS-INDUCED CONTRIBUTION TO BARYON NUMBER VIOLATION AT VERY HIGH-ENERGIES

The probability of baryon number violation and multiple production of W and Higgs bosons is known to be related to the instanton-anti-instan ton (IIBAR) interaction. We evaluate the Higgs-induced part of this in teraction, corresponding to ''streamline'' gauge configurations. As it is known to be repulsive at large IIBAR distances, the question was r aised whether it can produce a ''second barrier'' and significantly re duce the tunneling probability. However, our results show that this is not the case.
