4D Tracking workshop
53/2-2002 - Berryessa
SLAC
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.

Introduction
Workshop charge:
The central question driving this workshop is: What are the best technologies for developing a 4D tracker over the next 10 years, and how can we effectively integrate them? While this question cannot be definitively answered today, it is clear that significant generic R&D is required. This R&D should progress from proof-of-principle demonstrations of individual components to the development of a 4D tracking system demonstrator—something capable of performing 4D tracking in a test beam environment.
The goal of this workshop is to formulate concrete proposals for a U.S. program that enables steady progress towards such a demonstrator. A key initial step will be defining the necessary requirements and specifications. This doesn't mean that individual technologies (such as sensors) need to be selected and fixed at this stage. However, a hybrid approach could be outlined, where different sensors can be integrated with a common readout chip, allowing flexibility as the technologies evolve.
As future applications like HL-LHC Phase 3, MUC, FCC-ee/ILC, and FCC-hh continue to take shape, we aim to identify specific challenges these applications will demand. By focusing on challenges that are achievable with current technology, we can explore options that will guide the development of future detector systems before moving into application-specific R&D.
The workshop will conclude with a short report summarizing the key findings and recommendations related to these charge questions.
