Abstract

It has been recognized for some time that grand unified monopoles may catalyze ΔB ≠ 0 processes. We obtain model-independent upper bounds on the rates for such reactions from the survival of the baryon number generated in the early universe and from present-day baryon stability. These constraints are compatible with recent estimates of large baryon number violating monopole cross sections, but a monopole flux close to present experimental upper limits could be detectable in forthcoming baryon decay experiments. We mention signatures for monopole-induced baryon "decay" and point out that it could be used to solve the "energy crisis".
