R-parity as a residual gauge symmetry : probing a theory of cosmological dark matter

TL;DR

This paper proposes a non-supersymmetric model where R-parity emerges from gauge symmetry breaking, providing a viable Dirac fermion WIMP dark matter candidate detectable in future experiments.

Contribution

It introduces a novel non-supersymmetric framework where R-parity is a residual gauge symmetry, linking dark matter properties to gauge symmetry breaking.

Findings

Dark matter mass around 2-5 TeV consistent with LHC constraints

Direct detection prospects for nuclear recoil experiments

Lepton flavor violation and meson flavor changing rates within experimental reach

Abstract

We present a non-supersymmetric scenario in which the R-parity symmetry $R_P = (-1)^{3(B-L)+2s}$ arises as a result of spontaneous gauge symmetry breaking, leading to a viable Dirac fermion WIMP dark matter candidate. Direct detection in nuclear recoil experiments probes dark matter masses around $2-5$ TeV for $M_{Z^{\prime}} \sim 3-4$ TeV consistent with searches at the LHC, while lepton flavor violation rates and flavor changing neutral currents in neutral meson systems lie within reach of upcoming experiments.
