Neutrino flux normalization to enable precise CEvNS analysis

The COHERENT Collaboration has its first heavy-water Cherenkov detector module deployed in the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory (ORNL), in the same location where CEvNS events have been observed in cesium iodine, argon, and germanium. This detector, in combination with the second module (light water), has the goal of lowering the neutrino flux uncertainty at the SNS from 10% to only 2-3%, which will impact data analyses from COHERENT detectors from past, present, and future. Precise knowledge of the neutrino flux is crucial to enable accurate testing of the Standard Model, probing non-standard neutrino interactions (NSI), and searches for new physics, as this detector will continue to collect data for many more years. In this talk, I will present initial results for this detector from the 2024 science run, while the SNS beam was on.
