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

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 $SU(3)_L$. 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 $B-L$ 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 $Z$ with leptons govern lepton flavor violating processes such as $mu rightarrow 3e$, $murightarrow e bar{ u}_mu u_e$, $mu$-$e$ conversion in nuclei, semileptonic $taurightarrow mu(e)$ decays, as well as the nonstandard interactions of neutrinos with matter. This $Z$ may also set the dark matter observables and give rise to the LHC dilepton and dijet signals.
