Improved global fit to Non-Standard neutrino Interactions using COHERENT energy and timing data

Understand

We perform a global fit to neutrino oscillation and coherent neutrino-nucleus scattering data, using both timing and energy information from the COHERENT experiment.

• The results are used to set model-independent bounds on four-fermion effective operators inducing non-standard neutral-current neutrino interactions.
• We quantify the allowed ranges for their Wilson coefficients, as well as the status of the LMA-D solution, for a wide class of new physics models with arbitrary ratios between the strength of the operators involving up and down quarks.
• Our results are presented for the COHERENT experiment alone, as well as in combination with the global data from oscillation experiments.
