Description
The discovery of neutrino oscillations, awarded a Physics Nobel prize in 2015, imply massive neutrinos and lepton mixing, which are not accounted for within the framework of the Standard Model (SM). Therefore, from the theory viewpoint addressing this question requires going beyond the scope of the SM. In the last decades, numerous models have been put forward to explain the origin and smallness of neutrino masses. The most popular ones are those based on the seesaw mechanisms, in which new particles are introduced. In this work, we are interested in studying the phenomenology of the inverse seesaw (ISS) mechanism. Its main advantage lies in its testability, since it can be regarded as a low-energy neutrino mass mechanism. This opens the possibility of the detection of direct new physics signals at experiments like the Large Hadron Collider, and those searching for lepton number violating processes. Different ISS realisations are possible depending on the number of extra singlet fermions added to the SM. Our analysis of this mechanism will start with the identification of the scenarios that reproduce current experimental neutrino oscillation data and lepton mixing. The next step is to study their associated phenomenology comprised of rare processes, experimental signals and further low-energy effects.
