A New QCD Facility at the M2 beamline of CERN SPS — •Jan Friedrich for the COMPASS collaboration — Physik-Department, Technische Universität München

In view of completing the current physics programme of the COMPASS collaboration in 2021, ideas are shaped up for future measurements in the context of QCD with a refurbished and upgraded detector in the same experimental hall at the M2 beamline of the CERN SPS with 100--200~GeV beam energies. They range from high-energy elastic muon scattering for a proton radius measurement, with rather modest changes to the COMPASS setup, to upgrading the beamline with a radiofrequency separation of the hadron beam components, allowing e.g. for a strongly enriched kaon beam. This will allow measurements of the kaon parton distributions via the Drell-Yan process, and the kaonic excitation spectrum through diffractive dissociation. Further ideas, amongst others, concern measurements of antiproton production cross-sections, as of interest for Dark Matter Search, hadron spectroscopy with annihilation processes initiated by the antiproton beam component, and hard exclusive reactions using a muon beam on a transversely polarised target. Status and timelines of the project will be discussed.
