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…

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…
