Probing the supersymmetric grand unified theories at the future proton-proton colliders and Hyper-Kamiokande experiment

A Reexamination of Proton Decay in Supersymmetric Grand Unified Theories

We reconsider dimension–five proton decay operators, making semiquantitative remarks which apply to a large class of supersymmetric GUTs in which the short-distance operators are correlated with the fermion Yukawa couplings. In these GUTs, which include minimal SU(5), the operators (udi ) (djντ ), induced by charged Higgsino dressing, completely dominate for moderate to large tan β. The rate fo...

Proton Decay in the Supersymmetric Grand Unified Models

In this article we review proton decay in the supersymmetric grand unified models.

SUPPRESSION OF d = 5 OPERATOR INDUCED PROTON DECAY IN SUPERSYMMETRIC GRAND UNIFIED THEORIES

The proton decay in supersymmetric (SUSY) Grand Unified Theories (GUTs), where the special mechanism provides the natural suppression of the dimension 5 (d = 5) operators, was studied. Due to this mechanism, d = 5 operator induced proton decay takes place only through the mixing of light generation fermions with those from third generation and crucially depends on the structure of fermion mass ...

Supersymmetric Grand Unified Theories and Yukawa Unification

Status of Supersymmetric Grand Unified Theories

We begin with a brief discussion of the building blocks of supersymmetric grand unified theories. We recall some of the compelling theoretical reasons for viewing supersymmetric grand unification as an attractive avenue for physics beyond the standard model. This is followed by a discussion of some of the circumstantial evidence for these ideas. Invited Speaker at the XII DAE Symposium on High ...
