Non-standard Neutrino Interactions in Light Mediator Models
Speaker: Ankur Verma (Texas A&M University)
The non-standard interactions (NSI) in the neutrino sector are a well- motivated phenomenological approach to understand the new physics in the neutrino sector. Non standard neutrino-electron interaction mediated by light scalar/vector mediator arises naturally in many low-scale models. We also propose one such new model with a light scalar mediator. [...]Light Dark Matter Search in Stopped Pion Experiments
Speaker: Wei-Chih Huang (Texas A&M University)
We study inelastic dark matter-nucleus scattering in stopped pion experiments by nuclear shell model. We find that the inelastic scattering is dominated by Gamow-Teller (GT) transition. We use nuclear shell model code, BIGSTICK, to calculate GT transitions and the deexcitation photons for the nuclei such as Na-23, Ar-40, and I-127. [...]
