Does Quark Mixing play a role in the Lepton Sector?

High Energy Physics - Phenomenology 2023-04-17 v1

Abstract

We suggest a simple relation between the quark and the lepton mixing within the framework of type-I seesaw mechanism. We show that within our ansatz the empirical King-Mohapatra-Smirnov relation, which suggests a connection between the CKM and PMNS mixing where V13PMNS12sin(θC)|V^\text{PMNS}_{13}|\approx \frac{1}{\sqrt{2}}\sin(\theta_C) , can be derived. This is possible within a restricted region of the Dirac and Majorana mass parameters.
