Description
We study the sensitivity of COHERENT-like experiments to non-standard contributions within the so-called $\nu$WEFT framework. The latter is the most general low-energy effective field theory that includes not only the light SM fields but also additional right-handed Dirac neutrinos.
Our analysis uses the framework presented at "Consistent QFT description of non-standard neutrino interactions", which makes use of the full freedom of EFT's. This allows us, for the first time, to include flavor-general New Physics effects in neutrino production (pion and muon decays) and neutrino detection (through Coherent Elastic Neutrino-Nucleus Scattering). The versatility of this framework also allows to easyly study different NP scenarios, as was shown in the letter "Muon-decay parameters from COHERENT".
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. We use current COHERENT data to set constraints on the corresponding effective operators, and we estimate the sensitivity of future measurements.
