On the Renormalization of Neutrinos in the Seesaw Extension of the Two-Higgs Doublet Model

摘要

We present the complex mass renormalization scheme for mixed Majoranafermions using the Weyl spinor notation. Showing the expressions forfield and mass renormalization constants, we discuss the differences to theon-shell renormalization scheme. Working in a seesaw extended two-Higgsdoublet model, we apply the complex mass scheme for neutrino masses andmixings.
