Searches for New Physics at the Edge of Absolute Zero - Livestream

  • Why is there something in the universe instead of nothing?
  • What is the nature of the dark matter that constitutes ∼85% of the matter content of the universe?

Each of these two questions brings together physics on the largest of observable scales with the behavior of particles on the smallest of scales. Why matter formed and what caused it to cluster into galaxies and stars are among the most fundamental open questions in physics today. And the answers may lie in understanding the breakdowns of the Standard Model. In this talk, I will discuss the search for Neutrinoless Double Beta Decay, a lepton number violating decay that could help explain the matter dominance of the universe. I will describe the CUORE experiment, a tonscale bolometeric detector that searches for this and other rare decays, and the R&D on multiplexed TES sensors that could be instrumental in a next-generation experiment. I will then discuss the axion and its reemergence as a leading dark matter candidate. I will describe the ABRACADABRA-10 cm demonstrator experiment at MIT and present results from its recent searches for axion dark matter. Finally, I will describe the DMRadio program - a joining of ABRACADABRA-10 cm with the DMRadio-Pathfinder program at SLAC - and its prospects of probing some of the most interesting axion dark matter parameter space as a full-fledged, next-generation dark matter experiment.
