Constraints on neutrino lifetime from the Sudbury Neutrino Observatory
Physical Review DJeff Secrest et al.
2019 The long baseline between Earth and the Sun makes solar neutrinos an excellent test beam for exploring possible neutrino decay. The signature of such decay would be an energy-dependent distortion of the traditional survival probability which can be fit for using well-developed and high-precision analysis methods.
Search for invisible modes of nucleon decay in water with the SNO+ detector
Physical Review DJeff Secrest et al.
2019 This paper reports results from a search for nucleon decay through invisible modes, where no visible energy is directly deposited during the decay itself, during the initial water phase of SNO+. However, such decays within the oxygen nucleus would produce an excited daughter that would subsequently deexcite, often emitting detectable gamma rays.
Tests of Lorentz invariance at the Sudbury Neutrino Observatory
Physical Review DJeff Secrest et al.
2018 Experimental tests of Lorentz symmetry in systems of all types are critical for ensuring that the basic assumptions of physics are well founded. Data from all phases of the Sudbury Neutrino Observatory, a kiloton-scale heavy water Cherenkov detector, are analyzed for possible violations of Lorentz symmetry in the neutrino sector.
Search for neutron-antineutron oscillations at the Sudbury Neutrino Observatory
Physical Review DJeff Secrest et al.
2017 Tests on B-L symmetry breaking models are important probes to search for new physics. One proposed model with Δ(B-L)=2 involves the oscillations of a neutron to an antineutron. In this paper, a new limit on this process is derived for the data acquired from all three operational phases of the Sudbury Neutrino Observatory experiment.
Current Status and Future Prospects of the SNO+ Experiment
Adv.High Energy Phys.Jeff Secrest et al.
2016 SNO+ is a large liquid scintillator-based experiment located 2 km underground at SNOLAB, Sudbury, Canada. It reuses the Sudbury Neutrino Observatory detector, consisting of a 12 m diameter acrylic vessel which will be filled with about 780 tonnes of ultra-pure liquid scintillator. Designed as a multipurpose neutrino experiment, the primary goal of SNO+ is a search for the neutrinoless double-beta decay (0) of ^130Te.
