“…This flip converts the flavor matters in quark sector to the lepton sector as well as leads to the anomalies in interaction of neutrinos with matter [10]. The lepton flavor violating decays of charged leptons and the SM-like Higgs boson in this model were investigated, all of which were well below experimental bounds [9][10][11].…”

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 µ → 3e, µ → eν µ ν e , µ-e conversion in nuclei, semileptonic τ → µ(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. PACS numbers: 12.60.-i arXiv:1906.05240v1 [hep-ph]

“…• LFV decays of charged leptons were analyzed in the context of the inverse seesaw model [22], of effective field theory [26][27][28][29], of 2HDMs [28,30,31], and of the flipped 3-3-1 model [32]. The current experimental and theoretical situation for these decays is reviewed in ref.…”

We evaluate the decays $$ {\ell}_1^{\pm } $$ ℓ 1 ± → $$ {\ell}_2^{\pm}\gamma $$ ℓ 2 ± γ , Z → $$ {\ell}_1^{+}{\ell}_2^{-} $$ ℓ 1 + ℓ 2 − , and h → $$ {\ell}_1^{+}{\ell}_2^{-} $$ ℓ 1 + ℓ 2 − , where ℓ1 and ℓ2 are charged leptons with different flavours and h is the scalar particle with mass 125.25 GeV, in a two-Higgs-doublet model where all the Yukawa-coupling matrices conserve the lepton flavours but the Majorana mass terms of the right-handed neutrinos break the flavour lepton numbers. We find that (1) the decays $$ {\ell}_1^{\pm } $$ ℓ 1 ± → $$ {\ell}_2^{\pm}\gamma $$ ℓ 2 ± γ require large Yukawa couplings and very light right-handed neutrinos in order to be visible, (2) the decays Z → $$ {\ell}_1^{+}{\ell}_2^{-} $$ ℓ 1 + ℓ 2 − will be invisible in all the planned experiments, except in a very restricted range of circumstances, but (3) the decays h → $$ {\ell}_1^{+}{\ell}_2^{-} $$ ℓ 1 + ℓ 2 − may be detected in future experiments for rather relaxed sets of input parameters.
