Description
COMPASS is a modern fixed target experiment at a secondary beam of the Super Proton Synchrotron at CERN. The purpose of the experiment is the study of hadron structure and hadron spectroscopy with muon and hadron beams of high intensity. The COMPASS setup is a multipurpose universal spectrometer based on two analysing magnets and equipped with various tracking detectors, electromagnetic and hadron calorimeters, muon filters and Cherenkov detectors for particle identification. COMPASS has an intensive physics programme which includes the following topics: study of nucleon spin structure in semi-inclusive deep inelastic scattering and Drell-Yan process; measurement of the generalized parton distributions for the nucleon in reactions of deeply virtual Compton scattering and deeply virtual meson productions; search for new hadronic states and study of their production mechanisms; test of low-energy QCD models in Primakoff reactions. A physics programme for the period after 2020 is under discussion.
