The HUNTER Sterile Neutrino Search Experiment
Abstract
The HUNTER experiment (Heavy Unseen Neutrinos from Total Energy-momentum Reconstruction) is a search for sterile neutrinos with masses in the keV range. The neutrino missing mass will be reconstructed from 131-Cs electron capture decays occurring in a magneto-optically trapped sample. Reaction-microscope spectrometers will be used to detect all charged decay products with high solid angle efficiency and LYSO scintillators read out by silicon photomultiplier arrays detect x-rays, each with sufficient resolution to reconstruct the neutrino missing mass. The overall design of this W. M. Keck Foundation-funded experiment will be discussed and simulations shown. Upgrades which would improve the mixing angle sensitivity by orders of magnitude will be described.
We thank the W. M. Keck Foundation and our respective universities for financial support of HUNTER.- Publication:
