Radiative Seesaw Model with Baryon Number Violation and Upper Limit on Neutron-anti-Neutron Transition Time
Rabindra N. Mohapatra, Nobuchika Okada
The minimal scotogenic model where small neutrino masses arise via radiative seesaw, is known to provide a unified framework for neutrino mass and origin of matter via leptogenesis…
Avoiding Blindness in Baryon Number Violating Processes: Free-Beam and Intranuclear Paths to Neutron-Antineutron Transitions
Joshua L. Barrow, Peter Fierlinger, Yuri Kamyshkov +4
Experimental searches for neutron--antineutron () transitions can be considered via two approaches: conversion in free-neutron beams and intranuclear transfor…
Matter-Dark Matter Coincidence and Mirror World
Rabindra N. Mohapatra, Nobuchika Okada
Why matter and dark matter contents of the universe are of the same order of magnitude, is one of the puzzles of modern cosmology. At the face of it, this would seem to point towar…
Accidental Peccei-Quinn Symmetry From Gauged U(1) and a High Quality Axion
K. S. Babu, Bhaskar Dutta, Rabindra N. Mohapatra
We construct explicit models that solve the axion quality problem originating from quantum gravitational effects. The general strategy we employ is to supplement the Standard Model…
Hybrid SO(10) Axion Model Without Quality Problem
K. S. Babu, Bhaskar Dutta, Rabindra N. Mohapatra
Invisible axion models that solve the strong CP problem via the Peccei-Quinn (PQ) mechanism typically have a quality problem that arises from quantum gravity effects which violate…
Radiative Origin of Fermion Mass Hierarchy in Left-Right Symmetric Theory
Sudip Jana, Sophie Klett, Manfred Lindner +1
Despite the remarkable success of the Standard Model, the hierarchy and patterns of fermion masses and mixings remain a profound mystery. To address this, we propose a model employ…
Effects of Neutron-Antineutron Transitions in Neutron Stars
Itzhak Goldman, Rabindra N. Mohapatra, Shmuel Nussinov +1
We analyze effects of neutron-antineutron transitions in neutron stars, specifically on (i) cooling, (ii) rotation rate, and (iii) for binary pulsars, the increase in the orbital p…
Explanation of the 95 GeV and excesses in the Minimal Left-Right Symmetric Model
P. S. Bhupal Dev, Rabindra N. Mohapatra, Yongchao Zhang
We propose a simple interpretation of the excesses reported by both CMS and ATLAS groups at 95 GeV together with the LEP excess in the channel around the same mass…
Long-lived doubly charged scalars in the left-right symmetric model: catalyzed nuclear fusion and collider implications
Evgeny Akhmedov, P. S. Bhupal Dev, Sudip Jana +1
We show that the doubly charged scalar from the -triplet Higgs field in the Left-Right Symmetric Model has its mass governed by a hidden symmetry so that its value can be…
Predictive Dirac Neutrino Spectrum with Strong CP Solution in Unification
K. S. Babu, Rabindra N. Mohapatra, Anil Thapa
We develop a grand unified theory of matter and forces based on the gauge symmetry with parity interchanging the two factor groups. Our main motivation for…
Vacuum structure of the left-right symmetric model
P. S. Bhupal Dev, Rabindra N. Mohapatra, Werner Rodejohann +1
The left-right symmetric model (LRSM), originally proposed to explain parity violation in low energy processes, has since emerged as an attractive framework for light neutrino mass…
Long Lived Light Scalars as Probe of Low Scale Seesaw Models
P. S. Bhupal Dev, Rabindra N. Mohapatra, Yongchao Zhang
We point out that in generic TeV scale seesaw models for neutrino masses with local symmetry breaking, there is a phenomenologically allowed range of parameters where the Hig…

We point out that if the baryon number violating neutron-antineutron oscillation is discovered, it would impose strong limits on the departure from Einstein's equivalence principle…

If neutrino masses arise from a TeV-scale minimal Left-Right seesaw model, the ensuing extended Higgs sector with neutral, singly and doubly-charged scalars has a plethora of impli…
