Neutrino Mass, Dark Matter, and Leptogenesis
It is proposed that dark matter is the origin of neutrino mass, thereby linking inexorably two undisputed (and seemingly unrelated) pieces of evidence for physics beyond the Standard Model. Leptogenesis at the TeV scale may also be possible, as well as a measurable contribution to the muon anomalous magnetic moment. Talk at NOW2006, Conca Specchiulla, Otranto, Italy.
متن کاملEffects of Lightest Neutrino Mass in Leptogenesis
The effects of the lightest neutrino mass in “flavoured” leptogenesis are investigated in the case when the CP-violation necessary for the generation of the baryon asymmetry of the Universe is due exclusively to the Dirac and/or Majorana phases in the neutrino mixing matrix U . The type I see-saw scenario with three heavy right-handed Majorana neutrinos having hierarchical spectrum is considere...
متن کاملConstraints 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 کاملNeutrino Mass Matrix with Two Zeros and Leptogenesis
The leptogenesis is studied in the neutrino mass matrix with two zeros, which reduces the number of independent phases of the CP violation. These texture zeros are decomposed into the Dirac neutrino mass matrix and the right-handed Majorana one in the see-saw mechanism. It is found that there are six textures for the Dirac neutrino mass matrix, among which one texture with three zeros has three...
متن کاملVarious Realizations of Leptogenesis and Neutrino Mass Constraints
Following the recent convincing evidence for neutrino oscillations, leptogenesis has become a well motivated possible explanation of the origin of the baryon asymmetry of the universe. In these proceedings, after a short introduction on the three basic ingredients of leptogenesis, we will extend the discussion of Ref. along two main directions. First, in the framework of the usual seesaw model ...
