We give analytic approximations to the baryon asymmetry produced by thermal leptogenesis with hierarchical right-handed neutrinos. Our calculation includes flavour-dependent washout processes and CPâ€¦ (More)

The construction of an effective 3D theory at high temperatures for the MSSM as a model of electroweak baryogenesis is discussed. The analysis for a single light scalar field shows, that given theâ€¦ (More)

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 numerical factorsâ€¦ (More)

We consider a generic model with four gauge singlets which generates successfully the right amount of baryon asymmetry through leptogenesis at the TeV scale. It also reproduces lefthanded neutrinoâ€¦ (More)

We consider a generic type of leptogenesis model which can successfully produce the correct value of the observed baryon number to entropy ratio. The main feature of this model is that it is a simpleâ€¦ (More)

We analyze the effective 3 dimensional theory previously constructed for the MSSM and multi-Higgs models to determine the regions of parameter space in which the electroweak phase transition isâ€¦ (More)

We consider a general symmetric (3 Ã— 3) mass matrix for three generations of neutrinos. Imposing the constraints, from the atmospheric neutrino and solar neutrino anomalies as well as from the CHOOZâ€¦ (More)

We study the role played in leptogenesis by the equilibration of lepton flavors, as could be induced in supersymmetric models by off diagonal soft breaking masses for the scalar lepton doublets mÌƒÎ±Î²,â€¦ (More)

We consider neutrino masses generated at tree level and at one loop, through fermionâ€“sfermion loop diagrams, in the MSSM with R-parity violation. Using the (3 Ã— 3) mass and mixing matrices for threeâ€¦ (More)

NEXT-DEMO is a high-pressure xenon gas TPC which acts as a technological testbed and demonstrator for the NEXT-100 neutrinoless double beta decay experiment. In its current configuration theâ€¦ (More)
