Predictive one-zero with vanishing sub-trace texture in neutrino mass matrix in light of dark matter and neutrinoless double beta decay
Ankush, Sangeeta Dey, Rishu Verma +3
In this work, we investigate a predictive class of neutrino mass matrices characterized by one texture zero and one vanishing sub-trace within the framework of the scotogenic model…
Neutrino Model in Left-Right Symmetric Linear Seesaw Augmented with Modular Group
Raktima Kalita, Mahadev Patgiri
In this work, we have implemented modular symmetry in the left-right symmetric linear seesaw model. Interestingly, such modular symmetry restricts the proliferation of flavon…
Study of neutrino mass matrices with vanishing trace and one vanishing minor
Sangeeta Dey, Mahadev Patgiri
In this work we carry out a systematic texture study of the neutrino mass matrix with the ansatzes - (i) one vanishing minor and (ii) the zero sum of the mass eigenvalues with the…
Normal versus inverted hierarchical models within symmetry
N. Nimai Singh, H. Zeen Devi, Mahadev Patgiri
We make a theoretical attempt to compare the predictions from normal and inverted hierarchical models, within the framework of symmetry. We consider three major theoretical i…
Numerical consistency check between two approaches to radiative corrections for neutrino masses and mixings
Mrinal Kumar Das, Mahadev Patgiri, N. Nimai Singh
We briefly outline the two popular approaches on radiative corrections to neutrino masses and mixing angles, and then carry out a detailed numerical analysis for a consistency chec…
Discriminating neutrino mass models using Type II seesaw formula
N. Nimai Singh, Mahadev Patgiri, Mrinal Kumar Das
In this paper we propose a kind of natural selection which can discriminate the three possible neutrino mass models, namely the degenerate, inverted hierarchical and normal hierarc…
New Uncertainties in QCD-QED Rescaling Factors using Quadrature Method
Mahadev Patgiri, N. Nimai Singh
In this paper we briefly outline the quadrature method for estimating uncertainties in a function of several variables and apply it to estimate the numerical uncertainties in QCD-Q…
Inverted Hierarchical Model of Neutrino Masses Revisited
Mahadev Patgiri, N. Nimai Singh
In this letter we highlight the inherent problems associted with the inverted hierarchical model of neutrinos with only three generations and suggest possible solutions within the…
Right-handed Majorana Neutrino Mass Matrices for Generating Bimaximal Mixings in Degenerate and Inverted Models of Neutrinos
Mahadev Patgiri, N. Nimai Singh
An attempt is made to generate the bimaximal mixings of the three species of neutrinos from the textures of the right-handed Majorana neutrino mass matrices. We extend our earlier…
Degenerate and Inverted Hierarchical Models of Majorana Neutrinos from See-saw Mechanism
N. Nimai Singh, Mahadev Patgiri
In order to explain the recently reported result on the double beta decay experiment, together with the earlier established data on LMA MSW solar and atmospheric neutrino…
LMA MSW Solution from the Inverted Hierarchical Model of Neutrinos
Mahadev Patgiri, N. Nimai Singh
We examine whether the inverted hierarchical model of neutrinos is compatible with the explanation of the large mixing angles (LMA)MSW solution of the solar neutrino problem. The l…
Bimaximal Mixings from the Texture of the Right-handed Majorana Neutrino Mass Matrix
N. Nimai Singh, Mahadev Patgiri
We study the origin of neutrino masses and mixing angles which can accomodate the LMA MSW solutions of the solar neutrino anomaly as well as the solution of the atmospheric neutrin…
