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) 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]

Muon conversion to an electron in nuclei in the minimal R-symmetric supersymmetric standard model

“…Some seesaw models with right-handed neutrinos [7][8][9][10][11][12][13], scalar triplets [14][15][16], fermion singlet [17], and fermion triplets [18] can have CRðμ − e; nucleusÞ close to the experimental sensitivity. There are a few studies within models of nonsupersymmetry (SUSY), such as unparticle model [19,20], littlest Higgs model [21,22], left-right symmetric models [23], 331 model [24], and so on. There are also a few studies within models of SUSY, such as the minimal supersymmetric Standard Model (MSSM) [25], R-parity violating SUSY [26], low-scale seesaw models of minimal supergravity [27], a minimal supersymmetric extension of the SM with local gauged B and L [28,29], the constrained minimal supersymmetric Standard Model-seesaw [30], μνSSM [31], and so on.…”

Multicomponent dark matter in noncommutative B − L gauge theory

“…We show that this theory provides multicomponent dark matter naturally for P ≥ 4. Whereas, the model with P = 3 yield single component dark matter, which has been well established in the literature [30,32,33,36,37,43,46].…”

Vectorlike leptons and inert scalar triplet: Lepton flavor violation, g−2 , and collider searches

“…3-3-1 models are based on the SUð3Þ C × SUð3Þ L × Uð1Þ N gauge symmetry and were originally introduced since they offer a plausible answer to the number of generations in the Standard Model. These models have been extensively studied in contexts such as dark matter [44][45][46][47][48][49][50][51][52][53][54][55][56], flavor physics [57][58][59][60][61], neutrino masses [62][63][64][65][66][67][68][69][70][71], and collider physics [72][73][74][75].…”
