98. Inverse Seesaw in NMSSM and 126 GeV Higgs Boson

Mr Bin He (University of Delaware)

06/05/2013, 14:00

We consider extensions of the next-to-minimal supersymmetric model (NMSSM) in which the observed neutrino masses are generated through a TeV scale inverse seesaw mechanism. The new particles associated with this mechanism can have sizable couplings to the Higgs field which can yield a large contribution to the mass of the lightest CP-even Higgs boson. With this new contribution, a 126 GeV...

176. Electroweak-scale RIght-handed Neutrino Model

AJINKYA KAMAT (University of Virginia)

If neutrino masses are realized through the see-saw mechanism, can the right-handed neutrinos be produced and detected at present and future colliders? A model of electroweak-scale right-handed neutrino (EW$\nu_R$) model was constructed six years ago, in which the right-handed neutrinos are members of mirror fermion weak doublets and where the Majorana masses of the right-handed neutrinos are...

36. Neutrino masses and freed leptogenesis

Dmitry Zhuridov (Wayne State University)

Observable nonzero neutrino masses and baryon asymmetry of the Universe can not be explained within minimal Standard Model. However many its extensions generate both the baryon asymmetry through leptogenesis (LG) scenario and the neutrino masses. The upper limit on the CP asymmetry relevant for LG with hierarchical heavy neutrinos, which is called Davidson-Ibarra bound, assumed to be model...

124. Radiative Scaling Neutrino Mass with A_4 Symmetry and Warm Dark Matter

Mr Ahmed Rashed (University of Mississippi)

06/05/2013, 14:45

A new scenario of the scotogenic model has been proposed where neutrino masses are not inversely proportional to some large mass scale. It comes from a one-loop mechanism with dark matter in the loop consisting of singlet Majorana fermions with masses of order 10 keV, and neutrino masses are scaled down from them by factors of about 10^−5. This model may be implemented with the non-Abelian...

127. Relating CKM and MNS Mixing and Predicting the Neutrino CP Phases

Heng-Yu Chen (U)

06/05/2013, 15:00

If all fermion mixing angles come from the mixing of the Standard Model fermions with SU(5) 5 + 5-bar multiplets, a simple connection between CKM and MNS mixing results, which allows the prediction of all three neutrino CP phases, the remaining neutrino mass, and non-trivial constraints on the s quark mass, the atmospheric neutrino angle, and other parameters.

53. A Golden A_5 Model of Leptons with a Minimal NLO Correction

Alexander Stuart (University of Southampton)

06/05/2013, 15:15

We propose a new A_5 model of leptons which corrects the LO predictions of Golden Ratio mixing via a minimal NLO Majorana mass correction which completely breaks the original Klein symmetry of the neutrino mass matrix. The minimal nature of the NLO correction leads to a restricted and correlated range of the mixing angles allowing agreement within the one sigma range of recent global fits...

38. Binary Tetrahedral Flavor Symmetry

Dr David Eby (University of North Carolina, Chapel Hill)

06/05/2013, 15:30

A study of the T' Model and its variants utilizing Binary Tetrahedral Flavor Symmetry. Our model endeavors to bridge two categories of particles, leptons and quarks, a unification made possible by the inclusion of additional Higgs particles, shared between the two fermion sectors and creating a single coherent system. This is achieved through the use of the Binary Tetrahedral symmetry group...
