Abstract Charged Lepton Flavour Violating (cLFV) decays constrain the relationship between the neutrino and the scalar sectors of the Grimus-Neufeld model (GNM), an appealing minimal model of neutrino masses. It turns out, that in the scenario, where

The Grimus−Neufeld model can explain the smallness of measured neutrino masses by extending the Standard Model with a single heavy neutrino and a second Higgs doublet, using the seesaw mechanism and radiative mass generation. The Grimus−Lavoura a

In the Grimus-Neufeld model (GNM) the neutrino mass generation from an extended Higgs sector leads to bounds from Charged Lepton Flavour Violating (cLFV) processes. Here we update bounds from the previous study by extending the parameter space to non

We show how the renormalization constant of the Higgs vacuum expectation value, fixed by a tadpole condition, is responsible for gauge dependences in various definitions of parameters in the $R_{\xi}$-gauge. Then we show the relationship of this reno

We present a basic formalism for using the Weyl spinor notation in Feynman rules. We focus on Weyl spinors with mixed Dirac and Majorana mass terms. To clarify the definitions we derive the Feynman rules from the path integral and present two example

We study the gauge dependence of the neutrino mass renormalization in a two Higgs doublet model, that is extended with one singlet seesaw neutrino. This model gives only one light neutrino a mass at tree level, while the second light mass is generate

We present the complex mass renormalization scheme for mixed Majorana fermions using the Weyl spinor notation. Showing the expressions for field and mass renormalization constants, we discuss the differences to the on-shell renormalization scheme. Wo
