Abstract

The hierarchy problem and the smallness of neutrino masses are two of the problems, which have been considered in the literature in the last years, are considered disconnected. Nevertheless, taking into account the last experimental results from LHC, new approaches have been proposed recently to solve the fine-tunning problem. One of such approaches uses the neutral naturalness principle, and it describes how the top quarks partners are simultaneously right-handed neutrinos, responsible to generate mass to active neutrinos. This postdoctoral proyect intends to explore the ideia in which fermions and scalars responsible for mass generation in the neutrino sector are composed particles coming from a strongly-interacting sector. This possibility is indeed very appealing since there is a large quantity of phenomenological and cosmological limits that can be considered to determine its viability.
