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

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.
