Description
We study the sensitivity of COHERENT-like experiments to non-standard contributions within the most general low-energy effective field theory that includes not only the light SM fields but also additional right-handed Dirac neutrinos, the so-called $\nu$WEFT framework.
Making use of the full freedom of EFT's, we include flavor-general New Physics effects in neutrino production (pion and muon decays) and neutrino detection (through Coherent Elastic Neutrino-Nucleus Scattering) for the first time. The versatility of this framework also allows to easily study different NP scenarios, as was shown in the letter "Muon-decay parameters from COHERENT".
We use current COHERENT data to set constraints on the corresponding effective operators, and we estimate the sensitivity of future measurements. Despite the generality, the results can be written in compact form and are easy to implement in existing or future analyses using effective nuclear charges.
