Measurement of Reactor Antineutrino Oscillations with 1.46 Kilotonne-Years of Data at SNO+

M. de Abreu, A. Allega, M. R. Anderson, S. Andringa et autres

The SNO+ Collaboration reports new results on reactor antineutrino oscillations using data acquired from May 2022 through July 2025. The spectral analysis of a flux dominated by nuclear reactors at 240, 340, and 350 km yields the mass-squared difference Δ m 21 …

Cosmogenic neutron production in water at SNO +

M Abreu, A. Allega, M. R. Anderson, S. Andringa et autres

Accurate measurement of the cosmogenic muon-induced neutron yield is crucial for constraining a significant background in a wide range of low-energy physics searches. Although previous underground experiments have measured this yield across various cosmogenic muon energies, SNO + is uniquely positioned due …

Position reconstruction in the DEAP-3600 dark matter search experiment

Prabal Adhikari, Rahaf Ajaj, M. Alpízar-Venegas, P.-A. Amaudruz et autres

Abstract In the DEAP-3600 dark matter search experiment, precise reconstruction of the positions of scattering events in liquid argon is key for background rejection and defining a fiducial volume that enhances dark matter candidate events identification. This paper describes three distinct position …

Search for inelastic dark matter-nucleus scattering with the PICO-60 CF$_{3}$I and C$_{3}$F$_{8}$ bubble chambers

E. Adams, B. Ali, I. J. Arnquist, D. Baxter et autres

PICO bubble chambers have exceptional sensitivity to inelastic dark matter-nucleus interactions due to a combination of their extended nuclear recoil energy detection window from a few keV to $O$(100 keV) or more and the use of iodine as a heavy target. Inelastic …

Snowmass 2021 Scintillating Bubble Chambers: Liquid-noble Bubble Chambers for Dark Matter and CE$ν$NS Detection

E. Alfonso-Pita, Michelanne Baker, E. Behnke, M. Bressler et autres

The Scintillating Bubble Chamber (SBC) Collaboration is developing liquid-noble bubble chambers for the quasi-background-free detection of low-mass (GeV-scale) dark matter and coherent scattering of low-energy (MeV-scale) neutrinos (CE$ν$NS). The first physics-scale demonstrator of this technique, a 10-kg liquid argon bubble chamber dubbed …
