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 |V^PMNS₁₃|≈ (1)/(√(2))sin(θ_C) , can be derived. This is possible within a restricted region of the Dirac and Majorana mass parameters.
