Scrutinizing the KNT model with vacuum stability conditions
Tim Huesmann, Michael Klasen, Vishnu P. K
The Krauss-Nasri-Trodden (KNT) model provides a unified framework for addressing the smallness of neutrino masses (by a three-loop radiative mechanism) and the dark matter abundanc…

Gravitational Wave Signature and the Nature of Neutrino Masses: Majorana, Dirac, or Pseudo-Dirac?
Sudip Jana, Sudip Manna, Vishnu P. K
The fermionic nature of neutrinos and the origin of their tiny masses remain unresolved issues in particle physics, intrinsically connected to lepton number symmetry-conserved for…

How Charged Can Neutrinos Be?
Sudip Jana, Michael Klasen, Vishnu P. K
We investigate how neutrinos may acquire small electric charges within the Standard Model framework while preserving electromagnetic gauge invariance. Instead of gauging the standa…
