Coherent elastic neutrino-nucleus scattering (CEvNS) is a process in
which a neutrino scatters off an entire nucleus and for which the
observable signature is a tiny nuclear recoil. It represents a
background for direct dark matter detection experiments, as well as a
possible signal for neutrinos from the Sun and supernovae.
Furthermore, because the process is cleanly predicted in the Standard
Model of particle physics, a measurement is sensitive to
beyond-the-Standard-Model physics. The process was first predicted in
1973. It was measured for the first time by the COHERENT
collaboration using the unique, high-quality source of
neutrinos from the Spallation Neutron Source (SNS) at Oak Ridge
National Laboratory and a cesium iodide crystal scintillator detector.
This talk will describe COHERENT's recent measurement of CEvNS, the
status and plans of COHERENT's suite of detectors at the SNS, and
future physics reach.
