Superunification at local high energy thresholds

ORAL

Abstract

It is postulated that supergravitational interactions interface with SM physics at local high energy thresholds, which are characterized by a partially broken version of E$_{8}$XE$_{8}$. The proposed threshold symmetry assigns specific quantum numbers to fields of spin 2 and spin 3/2 that are indicated by locally supersymmetric Lagrangians, and in this context, SUGRA interactions at the postulated high energy thresholds produce quark-lepton transitions or additional quark triplets (excited baryon states). Baryon structure is preserved, and only one exotic particle is required: a left handed (non-strange) version of the strange quark.
