I will discuss the two separate issues on neutrino physics. First, the new bounds on tensorial couplings of neutrinos to charged fermions from the existing limits on neutrino transition magnetic moments. Second, explanation of the atmospheric and solar neutrino data for the democratic neutrinos with only one mass splitting, using the effect of incoherence.

We consider charged Higgs and W' gauge boson contributions to the quasielastic, Δ-resonance, and deep inelastic processes in the tau-neutrino nucleon scattering ντ+N→τ^−+X and ν¯τ+N→τ^++X. These effects modify the standard model cross section for these processes and thus impact the extraction of the neutrino mixing angles θ23 and θ13. We include form factor effects in our calculations and find...

We use quasielastic electron scattering data on nuclear target to parametrize the enhancement to the transverse response functions in nuclear targets. This enhancement has been attributed to meson exchange currents in nuclei. We parametrize both the overall magnitude of the enhancement and the contribution to the width of the quasielastic peak.
The model is in good agreement with recent...

Liquid Argon Time Projection Chambers are quickly becoming one of the main detector technologies in neutrino physics. They offer very good 3D and calorimetric resolution and allow relatively easy construction of large mass detectors making them a prime candidate for future precision neutrino measurements. Surprisingly, there has been relatively little effort in calibrating these detectors. The...

Such a search can shed light on the Majorana nature of the neutrino (whether the neutrino is its own anti-particle), the absolute mass scale of neutrinos, and beyond standard model processes that violate lepton number conservation. The EXO-200 detector uses 200 kg of xenon with 80% enrichment in 136Xe...

The Project 8 experiment aims to measure the neutrino mass using tritium beta decays. Beta-decay electron energies will be measured with a novel technique: as the electrons travel in a uniform magnetic field their cyclotron radiation will be detected. The frequency of each electron's cyclotron radiation is inversely proportional to its total relativistic energy; therefore, by observing the...
