The physics reach of a low threshold (100 eV) scintillating argon bubble chamber sensitive to Coherent Elastic neutrino-Nucleus Scattering (CE$\nu$NS) from reactor neutrinos is studied. sensitivity the weak mixing angle, neutrino magnetic moment, and light $Z'$ gauge boson mediator are analyzed. A Monte Carlo simulation backgrounds performed assess their contribution signal. analysis shows that world-leading sensitivities achieved with one-year exposure for 10 kg at 3 m 1 MW$_{th}$ research...
The Scintillating Bubble Chamber (SBC) collaboration is developing liquid-noble bubble chambers for the detection of sub-keV nuclear recoils. These detectors benefit from electron recoil rejection inherent in moderately-superheated with addition energy reconstruction provided scintillation signal. ability to measure low-energy recoils allows search GeV-scale dark matter and measurement coherent elastic neutrino-nucleus scattering on argon MeV-scale reactor antineutrinos. first physics-scale...
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 nonstandard interactions are studied. results indicate that this detector could be able set stronger constraints than current limits by the recent COHERENT measurements. Considering best scenario, 100 kg located 30 m from $2000\text{ }\text{...
