Behavior of effective charges in e6 grand unification theory in curved spacetime

  • 23 Accesses

Abstract

The behavior of effective charges ξi(t) corresponding to the parameters of nonminimal coupling of scalar and gravitational fields in E6 Grand Unification Theory (GUT) in curve spacetimes is studied. It is shown that in a strong gravitational field ¦ξi(t)¦ grows indefinitely.
