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

D.T. Huong, D.N. Dinh, L.D. Thien and Phung Van Dong

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 avor 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 avor violating processes such as M -> 3e, M -> eV_MV_e, conversion in nuclei, semileptonic T -> M(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.
