New Physics searches in a low threshold scintillating argon bubble chamber measuring coherent elastic neutrino-nucleus scattering in reactors

Understand

The sensitivity to New Physics of a low threshold scintillating argon bubble chamber measuring coherent elastic neutrino-nucleus scattering in reactors is reported.

• Namely, light scalar mediators, sterile neutrino oscillations, unitarity violation, and non-standard interactions are studied.
• The results indicate that this detector could be able to set stronger constraints than current limits set by the recent COHERENT measurements.
• Considering the best scenario, a 100 kg detector located 30 m from a 2000 MW$_{th}$ reactor, a sterile neutrino search would cover most of the space parameter allowed from the reactor anti-neutrino anomaly fit.
