Abstract
Baryon number violation and multiple production of W and Higgs bosons are described semiclassically in terms of the instanton–anti-instanton valley. We find (i) two saddle points, one describing reflection from a barrier and the other describing tunneling through it. We find (ii) a critical energy ∼35 TeV where the cross section is suppressed as exp(-const/), but the formulas are no longer valid; (iii) however, depending on the (still uncertain) Higgs bosson action, the cross section at this point may be large enough to be observable.
