Upper Bound On Gluino Mass From Thermal Leptogenesis
Thermal leptogenesis requires the reheating temperature TR > ∼ 3 × 10 9 GeV, which contradicts a recently obtained constraint on the reheating temperature, TR < ∼ 10 6 GeV, for the gravitino mass of 100 GeV−10 TeV. This stringent constraint comes from the fact that the hadronic decays of gravitinos destroy very efficiently light elements produced by the Big-Bang nucleosynthesis. However, it is ...
متن کاملA lower bound on the right-handed neutrino mass from leptogenesis
In the seesaw model, the baryon asymmetry of the Universe can be generated by the decay of the lightest right-handed neutrino, νR. For a hierarchical spectrum of right-handed neutrinos, we show that there is a model independent upper bound on the CP asymmetry produced in these decays: ǫ < 3 mν3MνR/(8π〈Hu〉). This implies that ǫ and the mass MνR of the lightest right-handed neutrino are not indep...
متن کاملGluino mass from dynamical supersymmetry breaking.
We present a new mechanism for gluino mass generation in models of dynamical supersymmetry breaking. The mechanism requires two colored chiral superfields which feel a nonabelian gauge interaction such that a fermion condensate is formed at a scale of order 1 TeV. Renormalizable hidden sector models, which typically yield unacceptably light gauginos, become viable if a gauge singlet is coupled ...
متن کاملThermal leptogenesis in a model with mass varying neutrinos
In this paper we consider the possibility of neutrino mass varying during the evolution of the Universe and study its implications on leptogenesis. Specifically, we take the minimal seesaw model of neutrino masses and introduce a coupling between the right-handed neutrinos and the dark energy scalar field, the Quintessence. In our model, the right-handed neutrino masses change as the Quintessen...
متن کاملCP Violation and Lightest Neutrino Mass Effects in Thermal Leptogenesis
Effects of the lightest neutrino mass in “flavoured” leptogenesis when the CPviolation 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 are discussed. The type I see-saw scenario with three heavy right-handed Majorana neutrinos having hierarchical spectrum is considered. The “orthogonal” p...
