Dark matter and flavor changing in the flipped 3-3-1 model

Abstract

The flipped 3-3-1 model discriminates lepton families instead of the quark ones in normal sense, where the left-handed leptons are in two triplets plus one sextet while the left-handed quarks are in antitriplets, under SU(3)LSU(3)_L. We investigate a minimal setup of this model and determine novel consequences of dark matter stability, neutrino mass generation, and lepton flavor violation. Indeed, the model conserves a noncommutative BLB-L symmetry, which prevents the unwanted vacua and interactions and provides the matter parity and dark matter candidates that along with normal matter form gauge multiplets. The neutrinos obtain suitable masses via a type I and II seesaw mechanism. The nonuniversal couplings of ZZ' with leptons govern lepton flavor violating processes such as μ3e\mu \rightarrow 3e, μeνˉμνe\mu\rightarrow e \bar{\nu}_\mu\nu_e, μ\mu-ee conversion in nuclei, semileptonic τμ(e)\tau\rightarrow \mu(e) decays, as well as the nonstandard interactions of neutrinos with matter. This ZZ' may also set the dark matter observables and give rise to the LHC dilepton and dijet signals.
