29. Fermion mixing with geometrical CP violation and its tests at the LHC

Ivo de Medeiros Varzielas (TU Dortmund)

We construct for the first time a flavor model, based on the smallest discrete symmetry Delta(27) that implements spontaneous CP violation with a complex phase of geometric origin, which can actually reproduce all quark masses and mixing data. We show that its scalar sector has exotic properties that can be tested at the LHC.

45. Neutrino mass and baryon asymmetry in two right-handed neutrino model

We discuss the Standard Model which extended by two right-handed neutrinos. In this case, the tiny neutrino masses observed by neutrino oscillation experiments and the baryon asymmetry of the universe (BAU) can be explained by these right-handed neutrinos, simultaneously. Moreover, we focus on the testability of right-handed neutrinos by the direct search experiments. Then, we investigate...

32. Lepton mixing from groups Delta (3 n^2) and Delta (6 n^2)

Claudia Hagedorn (University of Padua and SISSA)

04/12/2012, 15:20

I will present a comprehensive study of mixing patterns which can be derived from a flavor group Delta (3 n^2) or Delta (6 n^2), if one assumes that the flavor group is broken to a subgroup Ge in the charged lepton and to another subgroup Gnu in the neutrino sector with Ge != Gnu.

51. Neutrino mass from d>5 effective operators in an SU(5) GUT with discrete symmetry

Martin Krauss (Wuerzburg University)

04/12/2012, 15:45

New physics models often come with an extended Higgs sector and additional (discrete) symmetries. We will show that in these models neutrino mass can be generated by higher-dimensional effective operators, which can be systematically studied. As a consequence new physics will appear at the TeV scale, which has phenomenological implications at the LHC, such as processes with displaced vertices...
