Observable n - anti-n Oscillations with New Physics at LHC

TL;DR

This paper investigates extensions of the MSSM with TeV scale vector-like multiplets that could lead to observable neutron-antineutron oscillations at the LHC, while remaining consistent with proton decay constraints.

Contribution

It proposes a new class of MSSM extensions involving vector-like multiplets and a U(1) symmetry that enable observable n-anti-n oscillations without conflicting with proton decay limits.

Findings

Potential LHC signatures of vector-like particles through quark decay modes

Theoretical framework allowing neutron-antineutron oscillations at accessible energies

Compatibility with existing proton decay experimental bounds

Abstract

We explore extensions of the MSSM in which TeV scale vector-like multiplets can mediate observable n-anti-n oscillations, without causing conflict with the proton decay experiments, with a U(1) symmetry playing an important role. The colored vector-like particles, in particular, may be found at the LHC through some decay modes arising from their direct couplings to quarks.
