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”.

Abstract:

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.
