Neutrino Masses with Inverse Hierarchy from Broken L_e-L_μ-L_τ: a Reappraisal

Guido Altarelli, Roberto Franceschini

We discuss a class of models of neutrino masses and mixings with inverse hierarchy based on a broken U(1)_F flavour symmetry with charge L_e-L_μ-L_τfor lepton doublets and arbitrar…

Dark Matter from an ultra-light pseudo-Goldsone-boson

Luca Amendola, Riccardo Barbieri

Dark Matter (DM) and Dark Energy (DE) can be both described in terms of ultra-light Pseudo-Goldstone-Bosons (PGB) with masses m_{DM} ~ 10^{-23}eV and m_{DE} <= 10^{-33}eV respectiv…

Dark Energy and Right-Handed Neutrinos

Riccardo Barbieri, Lawrence J. Hall, Steven J. Oliver +1

We explore the possibility that a CP violating phase of the neutrino mass matrix is promoted to a pseudo-Goldstone-boson field and is identified as the quintessence field for Dark…

Proton Lifetime from SU(5) Unification in Extra Dimensions

Maria Laura Alciati, Ferruccio Feruglio, Yin Lin +1

We provide detailed estimates of the proton lifetime in the context of simple supersymmetric SU(5) grand unified models with an extra compact spatial dimension, described by the or…
