Neutrino mass, dark matter and anomalous magnetic moment of muon in a model

A Biswas, S Choubey, S Khan - Journal of High Energy Physics, 2016 - Springer
A bstract The observation of neutrino masses, mixing and the existence of dark matter are
amongst the most important signatures of physics beyond the Standard Model (SM). In this …

Scalar assisted singlet doublet fermion dark matter model and electroweak vacuum stability

A Dutta Banik, AK Saha, A Sil - Physical Review D, 2018 - APS
We extend the so-called singlet doublet dark matter model, where the dark matter is an
admixture of a Standard Model singlet and a pair of electroweak doublet fermions, by a …

Neutrino mass and leptogenesis in a hybrid seesaw model with a spontaneously broken CP

R Pramanick, TS Ray, A Shaw - Journal of High Energy Physics, 2023 - Springer

models for neutrino mass where a complex vacuum expectation value of a singlet scalar …

Two-Zero Textures Based on A4 Symmetry and Unimodular Mixing Matrix

N Razzaghi, SMM Rasouli, P Parada, P Moniz - Symmetry, 2022 - mdpi.com
We propose a phenomenological model of two-zeros Majorana neutrino mass matrix based
on the A 4 symmetry, where the structure of mixing matrix is a unimodular second scheme of …

Textures of neutrino mass matrix from S4-flavor symmetry

N Chamoun, EI Lashin - Journal of High Energy Physics, 2025 - Springer
A bstract We study a texture of neutrino mass matrix characterized by two constraints
consisting of one equality and another antiequality between two elements corresponding to …

Predictive S4 flavon model with TM1 mixing and baryogenesis through leptogenesis

M Chakraborty, R Krishnan, A Ghosal - Journal of High Energy Physics, 2020 - Springer
A bstract We use S 4 discrete group to construct a neutrino flavour model which leads to TM
1 mixing and is consistent with the neutrino oscillation data. Using the model's constrained …

Flavoured leptogenesis and CPμτ symmetry

M Sen - Journal of High Energy Physics, 2020 - Springer
A bstract We present a systematic study of leptogenesis in neutrino mass models with μτ-
flavoured CP symmetry. In addition to the strong hierarchical N1-dominated scenario (N 1 …

Consequences of minimal seesaw with complex μτ antisymmetry of neutrinos

P Roy, A Ghosal - Journal of High Energy Physics, 2018 - Springer
A bstract We propose a complex extension of μτ permutation antisymmetry in the neutrino
Majorana matrix M ν. The latter can be realized for the Lagrangian by appropriate CP …

Minimally modified Altarelli-Feruglio model for neutrino masses and mixings and its experimental consequences

M Lei, JD Wells - Physical Review D, 2020 - APS
We present a simple modification of the Altarelli-Feruglio A 4 flavor symmetry model using a
minimal number of parameters congruous with the symmetries of the original theory. The …

Dynamic fermion flavor mixing through transition dipole moments

J Rafelski, A Steinmetz, CT Yang - arXiv preprint arXiv:2309.15797, 2023 - arxiv.org
We show that Majorana neutrino flavor mixing can be driven by transition dipole moments in
the presence of external electromagnetic fields. We demonstrate the sensitivity of the …
