Abstract: COHERENT is a multi-detector experiment with main focus to study Coherent Elastic neutrino-Nucleus Scattering (CEvNS) on several target nuclei using a stopped-pion neutrino flux generated at the Spallation Neutron Source (SNS) at Oak Ridge. Despite having a very large and precisely predicted by the standard model cross section, CEvNS had not been observed for decades after the process was theoretically postulated. This is due to the difficulty detecting the keV-scale nuclear recoil signature. CEvNS were first observed with the COHERENT 14,6 kg CsI detector. In this talk, we detail the first CsI result, review present status of measurements, and present future program of COHERENT collaboration in search for manifestation of a new physics beyond the Standard Model.
