Collaboration:
COHERENT
The COHERENT experiment aims to study coherent elastic neutrino nucleus scattering (CEvNS) with various nuclei using pulsed neutrinos provided by the Spallation Neutron Source at ORNL. The first observation of CEvNS was reported by the COHERENT collaboration with a 14 kg CsI detector. The present dataset with twice more statistics is being analyzed. In addition, COHERENT has a ~ 22 kg LAr detector and is planning to deploy a 2 t NaI array and a 14.4 kg p-type point-contact germanium detector array to demonstrate the characteristic N^2 dependence of the CEvNS cross section. Proposed high statistics CEvNS measurements from ton-scale detectors would open new channels to search for physics beyond the Standard Model such as non-standard neutrino interactions, accelerator produced dark matter, weak mixing angle and electromagnetic properties of neutrinos. These measurements will also provide studies of charge-current neutrino cross sections in an energy range important for supernova physics. The status of the COHERENT experiment along with the future experimental program involving the CEvNS measurements will be presented.
