Eric Dahl from Northwestern University will present a talk on “From dark matter to CEvNS: Why and how to operate a liquid-noble bubble chamber at a nuclear reactor”.
As dark matter searches approach the coherent neutrino scattering (CEvNS) fog, many cosmic frontier experimenters are exploring corresponding new physics opportunities in the neutrino sector. This is particularly true for GeV-scale dark matter searches, where sensitivity to solar neutrino CEvNS translates in principal to sensitivity to anti-neutrino CEvNS at nuclear reactors. I will review the motivation for reactor CEvNS measurements and the associated experimental challenges, which mirror many of the challenges in a low-mass dark matter search. I will focus in particular on the Scintillating Bubble Chamber (SBC) collaboration’s continuing development of liquid-noble bubble chambers, highlighting the features that make this technique a compelling candidate for both GeV-scale dark matter searches and reactor CEvNS studies, while calling out the variations on a theme needed to match the technique to these two distinct physics programs.
