Measuring coherent elastic neutrino nucleus scattering with COHERENT

The COHERENT experiment measures coherent elastic neutrino nucleus scattering (CEvNS) with a multitude of different detection technologies at Oak Ridge National Laboratory's Spallation Neutron Source (SNS). Neutrinos generated by the SNS have an energy below 50 MeV, enabling coherent neutral current interactions in which the neutrino interacts with the nucleus as a whole. These elastic interactions result in nuclear recoils measurable with low-threshold detectors.

In this talk, I will provide an overview of the recent experimental efforts including the liquid argon, high-purity germanum and sodium iodide detectors. In particular, I will show first results from the summer 2023 SNS beam period with the newly-deployed HPGe detectors. The low noise and excellent energy resolution make it possible to access a lower recoil energy region in comparison to the previous CEvNS measurements, with reduced systematic uncertainties. I will also discuss BSM physics analyses such as accelerator-produced dark matter and the future physics opportunities at the second target station at SNS.
