Title:Axion Dark Matter Detection in an RF Cavity
Host: Da Liu
Room: 432
Abstract: I will present the recently proposed approach to detect photon-coupled dark matter axions in an RF cavity haloscope. The approach relies on axion-mediated transitions between nearly-degenerate resonant modes, leading to parametrically enhanced signal power for light axions. We will discuss how a resonant signal is generated, and how it compares with traditional haloscope searches. We will also discuss noise sources. This approach could probe axion oscillation frequencies ranging from Hz to O(100) MHz, all while operating at GHz frequencies.

Title: Can DUNE detect solar neutrinos?
Abstract: There is a long-standing tension between Delta m^2 measured
from solar neutrino experiments SNO and Super-Kamiokande, and that
measured from the KamLAND reactor experiment. While the reactor
measurement is virtually free of matter effects, the solar results
depends on them strongly. Could the DUNE Far Detector make an
independent measurement using the CC nue interaction on argon? I will
present the potential sensitivity, and also discuss questions about
signal recognition, neutron transport, and other backgrounds. some of
which are just now starting to be answered by simulations and dedicated
small experiments at Los Alamos, such as ARTIE and ACED.
