Spontaneous breaking of global baryon number symmetry

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

We study the possibility that theU(1) B global symmetry associated with baryon number is spontaneously broken. We present realistic examples implemented in the context of a suitably extended standardSU(2) L×U(1)×SU(3)c model and of a composite model of quarks and leptons. The globalU(1) B symmetry in both cases is spontaneously broken at a relatively low mass scale without any conflict with observations. The dominant baryon number nonconserving process in these models obeys the ΔB=2 selection rule.
