INPA SEMINAR TALK
Date: October 4, 2024
Time: 12:00 pm – 1:00 pm
Location: Sessler Conference Room – 50A-5132 [Hybrid and In-Person]
Speaker: Max Smiley (UC Berkeley)
Title: Shining Lights: 8B Solar Neutrino Flux Measurement with SNO+ and R&D for Next-Generation Optical Neutrino Experiments
Abstract: Neutrino detection has been a crucial contributor to our understanding of physics for over half a century, with optical photon-based technology playing a prominent role. Large-scale, liquid-phase, unsegmented photon-based detectors continue to shed light on a broad array of physics, probing sources from the Sun to nuclear reactors, and from man-made neutrino beams to atmospheric interactions. In this talk, I discuss work with one such detector, SNO+, and in particular efforts to measure the ${}^8$B solar neutrino flux during its scintillator phase. The resulting measurement of $[5.74_{-0.77}^{+0.84}\text{(stat.)}] \times 10^{6}~\text{cm}^{-2}~\text{s}^{-1}$ gives confidence in the understanding of SNO+’s operations in this period and adds to the family of measurements made of this flux around the community. Additionally, for the past several years, much effort has been directed toward the development of a new paradigm known as “hybrid” detection, which aims to benefit from the two optical light emission mechanisms, Cherenkov radiation and scintillation, currently drawn on separately in today’s experiments. In the second part of this talk, I discuss explorations into the physics potential for neutrinoless double beta decay and CNO solar neutrino flux measurement at large-scales of this technology, as well as an examination of particle identification capability of the novel scintillating medium water-based liquid scintillator, a candidate hybrid detector material. These explorations provide a confirmation of the possibilities for hybrid detection and help pave the way for concrete realizations of these technologies at larger scales.
