Title: Searching for Beyond the Standard Model Physics with COHERENT Energy and Timing Data

Abstract

We search for beyond the standard model physics by combining COHERENT Collaboration energy and timing data. Focusing on light, ≲GeV mediators, we find the data favor a ~10–1000 MeV mediator, as compared to the standard model best fit at the ≲ 2σ level. The best-fit coupling range is g ~ 10–5 – 10–3. The timing data provide statistical information on the neutrino flavor distributions that is not attainable from the nuclear recoil energies alone. This result accounts for uncertainty in the effective size of the neutron distribution, and highlights the power of including uncertainties on experimental backgrounds, nuclear structure, and beyond the standard model physics.
