On weak angles in unified theories with more than one neutral current

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

It is illustrated that additional weak mixing angles arising in unified models larger than SU (5) become negligible quickly as one increases the masses of the new neutral bosons. Simultaneously the standard mixing angle approaches Θ w =3/8 at unification energy.
