The smallest neutrino mass
Sacha Davidson, Gino Isidori, Alessandro Strumia
We consider models where one Majorana neutrino is massless at tree level (like the see saw with two right-handed neutrinos), and compute the contribution to its mass m generated by…
Various definitions of Minimal Flavour Violation for Leptons
Sacha Davidson, Federica Palorini
Neutrino masses imply the violation of lepton flavour and new physics beyond the Standard Model. However, flavour change has only been observed in oscillations. In analogy with the…
Flavour Matters in Leptogenesis
A. Abada, S. Davidson, A. Ibarra +3
We give analytic approximations to the baryon asymmetry produced by thermal leptogenesis with hierarchical right-handed neutrinos. Our calculation includes flavour-dependent washou…
Basis-independent methods for the two-Higgs-doublet model II. The significance of tan(beta)
Howard E. Haber, Deva O'Neil
In the most general two-Higgs-doublet model (2HDM), there is no distinction between the two complex hypercharge-one SU(2) doublet scalar fields, Phi_a (a=1,2). Thus, any two orthon…
Flavour Issues in Leptogenesis
A. Abada, S. Davidson, F-X. J. Michaux +2
We study the impact of flavour in thermal leptogenesis, including the quantum oscillations of the asymmetries in lepton flavour space. In the Boltzmann equations we find different…
