The COHERENT experiment running at Oak Ridge National Laboratory has firmly established the existence of a new kind of neutrino interaction. This work, recently published in Physical Review Letters was led by IU physicists Dan Salvat and Rex Tayloe and was the Ph.D. work of Jacob Zettlemoyer. The experiment employed a cryogenic liquid argon device to see the faint signature of a recoil argon nucleus in response to coherent elastic neutrino-nucleus scattering -- called ''CEvNS''. This first detection of CEvNS from an argon nucleus backs up a 2017 observation on cesium-iodide by COHERENT and opens the door for future, higher-precision measurements of CEvNS for increased understanding of supernovae, nuclear structure, and dark matter.
