Description

Starting from a conformal model for the type-one seesaw, we use functional matching to integrate out a heavy scalar singlet completely at the one-loop level. Before integration, the vacuum expectation value of the heavy scalar singlet generates a mass for the heavy right-handed neutrinos and modifies the Higgs potential. The one-loop level matching results in meaningful modifications to the potential and heavy right-handed masses that are different from those discussed in literature [1, 2]. Lastly, we will discuss the possible connection to “neutrino option” conformal models that generate the Higgs potential from heavy neutrino loop effects [3].
