Neutrino phenomenology and dark matter in an $$A_4$$ flavour extended $$B-L$$ model

Abstract: We present an A 4 flavor extended B − L model for realization of eV scale sterile neutrinos, motivated by the recent experimental hints from both particle physics and cosmology. The framework considered here is a gauged B − L extension of standard model without the introduction of righthanded neutrinos, where the gauge triangle anomalies are canceled with the inclusion of three exotic neutral fermions N i (i = 1, 2, 3) with B − L charges − 4, − 4 and 5. The usual Dirac Yukawa couplings between the SM neutrinos… Show more

“…In the present left-right symmetric model with linear seesaw mechanism, the light neutrino masses are diagonalized by U TBM , U 13 containing the mixing angle θ and phases. The form of the mixing matrix is expressed in terms of θ, δ and other phases in the following way [56,57,69,70],…”

“…It is interesting to notice that many non-abelian discrete symmetries i.e., S 3 [28][29][30][31], A 4 [32][33][34][35], S 4 [36][37][38] etc. and continuous symmetries like U (1) B−L [39][40][41][42][43][44][45], U (1) Le−Lµ [46][47][48][49], U (1) H [50][51][52][53] etc. come to our rescue to develop the model and generate neutrino mass matrix which gives results in-accordance with experimental data.…”
