Constraints on neutrino masses from leptogenesis models
Upper bounds on the CP asymmetry relevant for leptogenesis are reexamined and found weaker than in previous literature, both for hierarchical and for quasi-degenerate righthanded neutrinos. Successful leptogenesis implies the usual lower bound on right-handed neutrino masses, and an upper bound on left-handed neutrino masses (which we obtain to be 0.15 eV at 3σ) only if right-handed neutrinos a...
متن کاملTowards constraints on the SUSY seesaw from flavour-dependent leptogenesis
We systematically investigate constraints on the parameters of the supersymmetric type-I seesaw mechanism from the requirement of successful thermal leptogenesis in the presence of upper bounds on the reheat temperature TRH of the early Universe. To this end, we solve the flavour-dependent Boltzmann equations in the MSSM, extended to include reheating. With conservative bounds on TRH, leading t...
متن کاملConstraints on SUSY Seesaw from Leptogenesis and LFV
We study constraints on the fundamental parameters of supersymmetric type I seesaw models imposed by neutrino data, charged lepton flavor violation, thermal leptogenesis and perturbativity of the neutrino Yukawa couplings.
متن کاملCMB constraints on seesaw parameters via leptogenesis
The possibility to explain the CMB measurement of the baryon asymmetry with leptogenesis results in stringent model independent constraints on some of the see-saw parameters. These include the quadratic mean of the light neutrino masses that has to be lower than ∼ 0.17 eV. Furthermore, for maximal CP asymmetry, the observed value of the baryon asymmetry determines a stringent relation for the t...
متن کاملLectures on Mirror Symmetry, Derived Categories, and D-branes 1. Mirror Symmetry from a Physical Viewpoint
This is an introduction to Homological Mirror Symmetry, derived categories, and topological D-branes aimed at a mathematical audience. In the last lecture we explain why it is necessary to enlarge the Fukaya category with coisotropic A-branes and discuss how to extend the definition of Floer homology to such objects. These lectures were delivered at IPAM, March 2003, as part of a program on Sym...
