  The International Muon Collider Collaboration (IMCC) [1] was established in
2020 following the recommendations of the European Strategy for Particle
Physics (ESPP) and the implementation of the European Strategy for Particle
Physics-Accelerator R&D Roadmap by the Laboratory Directors Group [2],
hereinafter referred to as the the European LDG roadmap. The Muon Collider
Study (MuC) covers the accelerator complex, detectors and physics for a future
muon collider. In 2023, European Commission support was obtained for a design
study of a muon collider (MuCol) [3]. This project started on 1st March 2023,
with work-packages aligned with the overall muon collider studies. In
preparation of and during the 2021-22 U.S. Snowmass process, the muon collider
project parameters, technical studies and physics performance studies were
performed and presented in great detail. Recently, the P5 panel [4] in the U.S.
recommended a muon collider R&D, proposed to join the IMCC and envisages that
the U.S. should prepare to host a muon collider, calling this their "muon
shot". In the past, the U.S. Muon Accelerator Programme (MAP) [5] has been
instrumental in studies of concepts and technologies for a muon collider.
