Scotogenic generation of realistic neutrino mixing with D5
Soumita Pramanick
A mechanism of radiative generation of realistic neutrino mixing at one-loop level with is presented in this paper. The process is demonstrated in two set-ups using…
Naturally small Yukawa couplings from trans-Planckian asymptotic safety
Kamila Kowalska, Soumita Pramanick, Enrico Maria Sessolo
In gauge-Yukawa systems embedded in the framework of trans-Planckian asymptotic safety we discuss the dynamical generation of arbitrarily small Yukawa couplings driven by the prese…
Scotogenic S3 symmetric generation of realistic neutrino mixing
Soumita Pramanick
Realistic neutrino mixing is achieved at one-loop level radiatively using symmetry. The model comprises of two right-handed neutrinos, maximally mixed to produce the…
Radiative generation of realistic neutrino mixing with
Soumita Pramanick
Radiative generation of realistic mixing in neutrino sector is studied at one-loop level in a scotogenic symmetric framework. A scheme of obtaining non-zero …
Ameliorating the popular lepton mixings with A4 symmetry: A see-saw model for realistic neutrino masses and mixing
Soumita Pramanick
A model for neutrino masses and mixing is devised appointing the see-saw mechanism. The proffered model is fabricated with a combination of Type -I and Type-II see-saw contribution…
Three-Higgs-doublet model under A4 symmetry implies alignment
Soumita Pramanick, Amitava Raychaudhuri
A model with three scalar doublets can be conveniently accommodated within an A4 symmetric framework. The A4 symmetry permits only a restricted form for the scalar potential. We sh…
A neutrino mass model with S3 symmetry and see-saw interplay
Soumita Pramanick, Amitava Raychaudhuri
We develop a see-saw model for neutrino masses and mixing with an S3\times Z3 symmetry. It involves an interplay of Type-I and Type-II see-saw contributions of which the former is…
A4-based see-saw model for realistic neutrino masses and mixing
Soumita Pramanick, Amitava Raychaudhuri
We present an -based model where neutrino masses arise from a combination of see-saw mechanisms. The model is motivated by several small mixing and mass parameters indicated by…
Relating small neutrino masses and mixing
Soumita Pramanick, Amitava Raychaudhuri
Experiments on neutrino oscillations have uncovered several small parameters, being a prominent one. Others are the solar mass splitting {\em vis-à-vis} the atmospheric on…
Are the small neutrino oscillation parameters all related?
Soumita Pramanick, Amitava Raychaudhuri
Neutrino oscillations reveal several small parameters, namely, , the solar mass splitting {\em vis-à-vis} the atmospheric one, and the deviation of from maximal mi…
Smallness of θ_{13} and the size of the Solar Mass Splitting: Are they related?
Soumita Pramanick, Amitava Raychaudhuri
Compared to the other neutrino mixing angles θ_{13} is small. The solar mass splitting is about two orders smaller than the atmospheric splitting. We show that it is possible that…
