$n-\overline{n}$ Oscillation in $S^1/Z_2\times Z_2'$ Orbifold $SU(5)$ GUT

TL;DR

This paper investigates neutron-antineutron oscillation and proton decay within an $SU(5)$ grand unified theory framework on an orbifold, providing explicit operator realizations for these baryon number violating processes.

Contribution

It introduces a novel realization of baryon number violating operators in an orbifold $SU(5)$ GUT, specifically addressing $n-ar{n}$ oscillation and proton decay mechanisms.

Findings

Explicit operators for $n-ar{n}$ oscillation are constructed.

Proton decay channels are analyzed within the orbifold GUT context.

The model predicts observable baryon number violation signatures.

Abstract

We explore the possibility of $B$ and $B-L$ violating processes, specifically proton decay and neutron-antineutron oscillation, using explicit realization of operators in the $SU(5)$ grand unified theory with an $S^1/Z_2 \times Z_2'$ orbifold space.
