Neutrino Mass, Mixing and CP

Seventy years have elapsed since Majorana's bold hypothesis about the neutrinos, and almost the same time since he dissappeared in misterious circunstances, a mistery yet as unresolved as the true nature of Neutrino. Probably we will never know what happened to the physicist but neutrinoless double deta decay experiments may unravel if the neutrino is its own antiparticle. I will offer a brief...

59. Spontaneous R-parity violation and the origin of neutrino mass

Supersymmetry

We study the phenomenology of supersymmetric models that explain neutrino masses through the spontaneous breaking of R-parity, finding strong correlations between the decays of the lightest neutralino and the neutrino mixing angles. In addition, the existence of a Goldstone boson, usually called majoron (J), completely modifies the phenomenology with respect to the standard picture, inducing...

63. Finite Unified Theories

Finite Unified Theories are N=1 supersymmetric Grand Unified Theories, which can be made all-loop finite, both in the dimensionless (gauge and Yukawa couplings) and dimensionful (soft supersymmetry breaking terms) sectors. This remarkable property, is based on the reduction of couplings at the quantum level. We plan first to present the scheme of reduction of couplings, then the conditions...
