Fermilab's MINERvA experiment is designed to make precision measurements of muon neutrino scattering cross sections on a variety of nuclear targets. Its 1-20 GeV energy range (which has since been increased for our current data-taking) should be of particular interest to PINGU. After introducing the MINERvA detector, I will describe several recently-published results that are already being...

Low-energy neutrinos can have de Broglie wavelengths that are larger than target nuclei.
At these energies, coherent elastic neutrino-nucleus scattering (CEvNS) is predicted to be the dominant interaction, yet it remains unseen.
Measuring CEvNS is difficult because elastic scattering deposits very little energy in a detector and neutron backgrounds are difficult to control, especially at...

Project 8 is developing a new approach to the tritium-endpoint method of direct neutrino mass measurement. First results from a proof-of-principle system demonstrate the Cyclotron Radiation Emission Spectroscopy technique by measuring the conversion electron spectrum of krypton-83m. I will provide an overview of the technique and released results, as well as future prospects.

Accelerator-Based Neutrino Physics
Recently, anomalies consistent with neutrino oscillations with mass splittings on the order of 1 eV2 have been observed. These anomalies have been seen in experiments measuring nue appearance and nue/nue-bar disappearance, while no corresponding evidence for muon neutrino disappearance has been detected. A common interpretation of the anomalies involves postulating the existence of one or...

Accelerator-Based Neutrino Physics
Neutrinos are treated as point particles in Monte Carlo simulations for predicting detector counting rate. In this talk, a theoretical study on possible conflict between point-particle and wave-packet pictures in accelerator neutrino experiments will be presented. It is a quantum-mechanical phenomenon that neutrino wave packets spread as they propagate in space. The effect of longitudinal...
