Neutrino parameters in the Planck-scale lepton number breaking scenario with extended scalar sectors

no code implementations21 Dec 2020 Cesar Bonilla, Johannes Herms, Alejandro Ibarra, Patrick Strobl

Two-loop effects on the right-handed neutrino masses can have an impact on the low-energy phenomenology, especially when the right-handed neutrino mass spectrum is very hierarchical at the cut-off scale.

Search for Light Exotic Fermions in Double-Beta Decays

no code implementations16 Dec 2020 Matteo Agostini, Elisabetta Bossio, Alejandro Ibarra, Xabier Marcano

The Standard Model of Particle Physics predicts the double-$\beta$ decay of certain nuclei with the emission of two active neutrinos.

Dark matter decay through gravity portals

1 code implementation2 Nov 2016 Oscar Catà, Alejandro Ibarra, Sebastian Ingenhütt

Motivated by the fact that, so far, the whole body of evidence for dark matter is of gravitational origin, we study the decays of dark matter into Standard Model particles mediated by gravity portals, i. e., through nonminimal gravitational interactions of dark matter.

We demonstrate that the SHiP experiment has a unique potential to discover new physics and can directly probe a number of solutions of beyond the Standard Model puzzles, such as neutrino masses, baryon asymmetry of the Universe, dark matter, and inflation
