177. Theory of Lepton Flavors

114. Non-Standard Neutrino Interactions in the mu tau sector

Warren Wright (Penn State)

This research focuses on Non-Standard Interactions and their effects on neutrino oscillations. In particular, we focus on the effects of the parameter ϵµτ on muon neutrino survival probability and the number of muons measured in IceCube's DeepCore detector. These effects are found to be sign asymmetric and an analytic model is presented that predicts points of maximum sign asymmetry....

81. Majorana Physics in the Flavor Ring

Michael Perez (University of Florida)

05/05/2014, 17:15

In this talk, we introduce the idea of the "Flavor Ring", a framework in which the simultaneous consideration of ideas from Grand Unification and flavor observables allow one to constrain models of flavor. Focusing on the neutrino sector and assuming the seesaw mechanism, we show how relations from SO(10) and the assumption of a diagonal up-quark Yukawa matrix, natural in terms of a family...

80. Accommodating $\theta_{13}$ within $SU(5)$

Jue Zhang (University of Florida)

Tri-bimaximal, Golden Ratio or Bimaximal matrix has long been considered as a good leading order parametrization for the neutrino mixing matrix. However, the recent discovery of non-zero $\theta_{13}$ neutrino mixing angle requires corrections to these leading order parametrizations. Those corrections may come from the quark sector, as in Grand Unified Theories Yukawa couplings of quarks and...

92. Obtaining a nonzero $\theta_{13}$ in lepton models based on $SO(3) \rightarrow A_4$

Wee Hao Ng (C)

The simplest lepton models based on $A_4$ symmetry predict $\theta_{13} = 0$ at tree level, which contradicts recent experimental data from Daya Bay and RENO. We study models where the $A_4$ symmetry arises as the unbroken subgroup of a spontaneous broken $SO(3)$ symmetry, and find that a nonzero $\theta_{13}$ arises naturally at tree level. Extra heavy fields required in the model mixes with...

7. Tests of lepton universality and lepton flavour violation in B decays

Nicola Anne Skidmore (STFC - Science & Technology Facilities Council (GB))

05/05/2014, 18:00

Heavy flavour decays allow to test lepton universality and flavour conservation. We review recent LHCb results on B->emu, searches for Majorana neutrinos in B->pimumu and test of lepton universality in B->llK.

96. Exploring lepton flavor violation at an electron-electron collider

Brandon Murakami (Rhode Island College)

05/05/2014, 18:15

Observation of flavor violation for charged leptons would be an unambiguous signal for physics beyond the standard model. Using existing low-energy constraints as a guide, we study charged lepton flavor violation at an electron-electron collider, a plausible option for the International Linear Collider. We demonstrate the complementarity of an observable for electron-electron collisions with...
