4D Tracking is a major new technology that will be transformative for future colliders. 4-dimensional tracking with ultra-fast timing and very fine spatial resolution will be key to addressing the increasing complexity of events at hadron colliders (HL-LHC and FCC-hh) and suppressing the beam-induced backgrounds at muon colliders. Higgs factories (FCC-ee/ILC) will utilize timing layers for ToF particle identification and long-lived particle searches. The purpose of this workshop is to bring the US community interested in 4D tracking together to discuss various efforts being pursued towards forming a collaboration to pursue 4D tracking detector R&D within the US. Such collaboration could help set requirements towards specific goals or demonstration projects, keep the community informed and encourage collaboration through regular meetings and/or workshops, etc. The goal is to have a discussion about what could be helpful to this community.
