Non-anomalous axions: lessons from the Majoron
Antonio Herrero-Brocal
We show that when an anomalous and a non-anomalous global symmetries are spontaneously and simultaneously broken, the resulting Nambu--Goldstone boson is associated with the non-an…
Beyond : as the underlying symmetry of the strong and electroweak interactions
Antonio Herrero-Brocal, Javier Perez-Soler, Avelino Vicente
The gauge principle is a cornerstone of particle-physics model building. Nevertheless, many constructions leave certain global redundancies ungauged. In this work, we take t…
Probing Dark Sector Particles Coupling to Neutrinos with Double Beta Decay
Noor-Ines Boudjema, Frank F. Deppisch, Antonio Herrero-Brocal +2
Motivated by the observation of non-zero neutrino masses and the potential for discovering physics beyond the Standard Model, numerous experiments are actively searching for neutri…
Minimal Majorana neutrino mass models
Antonio Herrero-Brocal, Avelino Vicente
We present an extension of the Casas-Ibarra parametrization that applies to all possible Majorana neutrino mass models. This framework allows us to systematically identify minimal…
Flavour and cosmological probes of Diracon models
Salvador Centelles Chuliá, Tim Herbermann, Antonio Herrero-Brocal +1
We present and analyze two minimal extensions of the Standard Model featuring a spontaneously broken global, chiral, and anomaly-free symmetry. This breaking generates nat…
