| Description | Speaker: Zhengkang Zhang Host: Title: Effective Field Theory of Dark Matter Direct Detection With Collective Excitations Zoom: https://zoom.us/j/186024391 Abstract: I will present a framework for computing dark matter direct detection rates via phonon and magnon excitations in crystal targets for general dark matter models. It consists of parameterizing dark matter interactions by a nonrelativistic EFT, and computing material responses to the EFT operators. Our work extends previous calculations that focused on simple models such as standard spin-independent interactions, and shows that new direct detection experiments that utilize collective excitations, such as SPICE, will have discovery potential over a broad range of dark matter theories. |
