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 $\mu \rightarrow 3e$, $\mu\rightarrow e \bar{\nu}_\mu\nu_e$, and $h\rightarrow \mu\tau$ as well as the nonstandard interactions of neutrinos with matter.
