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

Understand

We search for beyond the Standard Model (BSM) physics by combining COHERENT energy and timing data.

• Focusing on light, $\lesssim$ GeV mediators, we find the data favor a $\sim 10-1000$ MeV mediator as compared to the Standard Model (SM) best fit at the $\lesssim 2\sigma$ level.
• The best-fit coupling range is $g \sim 10^{-5}-10^{-3}$.
• The timing data provides statistical information on the neutrino flavor distributions that is not attainable from the nuclear recoil energies alone.
