The gauged $B - L$ symmetry is one of the simplest and well studied extension of standard model. In the conventional case, addition of three singlet right handed neutrinos each transforming as $-1$ under the $B - L$ symmetry renders it anomaly free. It is usually assumed that the $B - L$ symmetry is spontaneously broken by a singlet scalar having two units of $B - L$ charge, resulting in a natural implementation of Majorana seesaw mechanism for neutrinos. However, as we discuss in this…

Systematic analysis of Dirac neutrino masses from a dimension five operator

We perform a systematic study of the Dirac neutrino masses which arise from a dimension five effective operator with a singlet scalar. We identify all possible realizations of this operator at tree

Dark Matter and the elusive Z′ in a dynamical Inverse Seesaw scenario

A bstractThe Inverse Seesaw naturally explains the smallness of neutrino masses via an approximate B − L symmetry broken only by a correspondingly small parameter. In this work the possible dynamical

Inverse seesaw in A′_5 modular symmetry

We make an investigation of modular Γ′5 ≃ A′5 group in inverse seesaw framework. Modular symmetry is advantageous because it reduces the usage of extra scalar fields significantly. Moreover, the

Naturally small Dirac neutrino mass with intermediate SU(2)L multiplet fields

A bstractIf neutrinos are Dirac fermions, certain new physics beyond the standard model should exist to account for the smallness of neutrino mass. With two additional scalars and a heavy

Dirac neutrino mass generation from a Majorana messenger

The radiative type-I seesaw has been already implemented to explain the lightness of Majorana neutrinos with both Majorana and Dirac heavy fermions, and the lightness of Dirac neutrinos with Dirac

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

We present an $A_4$ flavor extended $\rm B-L$ model for realization of eV scale sterile neutrinos, motivated by the recent experimental hints from both particle physics and cosmology. The framework

Seesaw Dirac neutrino mass through dimension-six operators

In this paper, a followup of arXiv: 1802.05722, we describe the many pathways to generate Dirac neutrino mass through dimension-6 operators. By using only the Standard Model Higgs doublet in the



Quasi-Dirac neutrinos in a model with local B - L symmetry

In a model with B − L gauge symmetry, right-handed neutrinos may have exotic local B − L charge assignments: two of them with B − L = −4 and the other one having B − L = 5. Then, it is natural to

Gauge Trimming of Neutrino Masses

We show that under a new U(1) gauge symmetry, which is non-anomalous in the presence of one ''right-handed neutrino'' per generation and consistent with the standard model Yukawa couplings, the most

New U(1) gauge symmetry of quarks and leptons

Instead of anchoring the seesaw mechanism with the conventional heavy right-handed neutrino singlet, a small Majorana neutrino mass may be obtained just as well with the addition of a heavy triplet

Leptogenesis with Lepton-Number-Violating Dirac Neutrinos

Dirac neutrinos with lepton-number-violating interactions can give rise to a new leptogenesis mechanism. In its simplest renormalizable realization, based on a gauged B-L symmetry spontaneously
