Neutrino phenomenology in a left-right D4 symmetric model

Abstract

We present a minimal left-right symmetric flavor model and analyze the predictions for the neutrino sector. In this scenario, the Yukawa sector is shaped by the dihedral D 4 symmetry which leads to correlations for the neutrino mixing parameters. We end up with the four possible solutions within this model. We further analyzed the impact of the upcoming long-baseline neutrino oscillation experiment, DUNE. Due to its high sensitivity, it has been observed that the DUNE will be able to rule out two of the solutions. Finally, the predictions for the neutrinoless double beta decay and the lepton flavor violating process μ → eγ for the model have also been examined.

Neutrinoless double beta decay and sterile neutrino dark matter in extended left right symmetric model

“…A 4 is the discrete group of even permutations of four objects is the smallest non-Abelian group containing triplet irreducible representations. More importantly, flavor symmetry has been used within the framework of LRSM in very few works [67][68][69][70]. In some other important literatures extended LRSM is also discussed considering different dominant seesaw [53,56,[71][72][73].…”
