Title: Understanding Neutrinos, Nuclei, and the Standard Model with COHERENT

Abstract: The properties of neutrinos are central to understanding the Standard Model of particle physics and any new physics beyond it. Meanwhile, the nature of neutrino-matter interaction is a powerful probe of the weak response of nuclei, and it is crucial for refining the predicted signals in current and future neutrino experiments across a broad range of energies. Coherent Elastic Neutrino-Nucleus Scattering (CEvNS) is the most prevalent scattering channel for neutrino energies less than 100 MeV, and it is sensitive to a variety of beyond Standard Model phenomena and to the weak charge distribution of nuclei. The Oak Ridge Spallation Neutron Source (SNS) is a bright, pulsed source of low-energy neutrinos, and the SNS has a low-background basement corridor well-suited for neutrino detection. The COHERENT experiment employs a suite of detectors in this “Neutrino Alley” with a variety of target nuclei, permitting studies of new physics, dark matter, the properties of neutrinos, and nuclear structure. In this talk I will present new measurements of CEvNS cross sections and world-leading limits on accelerator-produced dark matter, and I will explore how our experiment probes nuclear and high-energy physics in our current and future experimental program.
