Minimal A4 Type-II Seesaw Realization of Testable Neutrino Mass Sum Rules
Salvador Centelles Chuliá, Ranjeet Kumar
We propose a flavour model based on an symmetry combined with a type-II seesaw mechanism for neutrino mass generation. The resulting neutrino mass matrix obeys a sum rule tha…

Radiative Dirac Neutrino Masses from Modular Symmetry in an Axion Model
Sin Kyu Kang, Ranjeet Kumar, Hiroshi Okada
We present a unified axion model framework that simultaneously addresses the origin of neutrino masses, leptonic flavor structure, the strong CP problem, and dark matter. The model…
