Implementing the neutrino option with the inverse seesaw model

The Neutrino Option is a scenario that, adopting the EFT approach, addresses two important issues of the Standard Model: the absence of a neutrino mass term in the SM Lagrangian and the lack of a dynamical origin for the Higgs potential. In this minimal scenario the neutrino masses and the Higgs potential are simultaneously generated through the matching contributions given by the Type 1 Seesaw model. This implementation of the Neutrino Option predicts a mass for the heavy neutrino of 10^6-10^7 GeV, which is far out of the energy range of current experiments, making this model untestable (at least for now). The aim of this project is to conduct a similar analysis by implementing the Neutrino Option with the Inverse Seesaw (ISS) mechanism. Using the additional freedom in the parameter space of the ISS, we show that it is possible to lower the prediction of the heavy mass down to 10^3-10^6 GeV, reaching experimentally testable energy scales. We first perform the analysis in the case of one flavour generation in order to get some order-of-magnitude predictions and we later introduce a more realistic flavour structure, which however is consistent with the results of the first case.
