Higgs mass scales and matterantimatter oscillations in grand unified theories
Abstract
A general discussion of mass scales in grand unified theories is presented, with special emphasis on Higgs scalars which mediate neutronantineutron (nanti n) and hydrogenantihydrogen (Hanti H) oscillations. The analogue of survival hypothesis for fermions naturally makes such particles superheavy, thus leading to unobservable lifetimes. If this hypothesis is relaxed, an interesting possibility of potentially observable nanti n and Hanti H transitions, mutually related arises in the context of SU(5) theory with spontaneously broken BL symmetry.
