Heavy neutrinos: The chosen ones to bring balance to physics
Manuel Gonz\'alez-L\'opez

TL;DR
This paper explores the hypothesis that heavy neutrinos could explain the mass of observed neutrinos and discusses extensions of the Standard Model involving these particles, analyzing their interactions and experimental detectability.
Contribution
It investigates the role of heavy neutrinos in extending the Standard Model to account for neutrino masses and explores their experimental signatures.
Findings
Heavy neutrinos could generate neutrino masses.
Extensions of the Standard Model include these neutrinos.
Potential experimental observations of heavy neutrino interactions.
Abstract
The Standard Model of Particle Physics has proven to be tremendously successful as the fundamental theory that describes the elementary particles that compose our Universe, as well as the interactions among them. Despite the countless experimental results that have ratified the theoretical predictions of this model, there are sound reasons to think it must be extended. Some are rather theoretical, while others are due to the observation of certain phenomena that the the Standard Model cannot explain. Chief among the latter is the massive nature of neutrinos, the most elusive particles in the Universe, which are rendered massless by the Standard Model. This contradiction establishes the starting point of this PhD thesis, which discusses the role of heavy neutrinos (a hypothetical new type of neutrino) as responsible of generating the mass of the observed neutrinos. Certain extensions of…
