Abstract:
We show that the monopole problem in Grand Unified Theories as well as the domain wall problem may be easily solved if the lepton number asymmetry in the Universe is large enough.
  • magnetic monopole
  • grand unified theory
  • domain wall
  • lepton number: asymmetry
  • defect: topological
