The Proposed CYGNUS Directional Nuclear Recoil Observatory

With WIMP-nucleon scattering limits approaching the neutrino floor, and coherent elastic neutrino-nucleus scattering (CEvNS) experimentally established, there is renewed interest in constructing a large-scale nuclear recoil observatory capable of detecting and distinguishing WIMP and CEvNS interactions via directionality. The CYGNUS proto-collaboration aims to deploy multiple gas-target time projection chambers (TPCs) to accomplish this. I will discuss the projected dark matter sensitivity and neutrino physics case for CYGNUS, and compare the suitability of different technological approaches.
