| description | COMPASS is a fixed-target experiment aimed to study the structure and dynamics of hadrons. Using a 190 GeV/c pion beam, the spectrum of light mesons is studied at four-momentum transfers squared to the target between 0:1 and 1:0 GeV2/c2. The flagship channel is the diffractive production of π−π−π+ final states for which COMPASS has recorded the world’s largest data sample. The determination of properties of known resonances, and the search for new states is also pursued in the π−π0π0 final state, and in centrally produced systems. The structure of light mesons is studied in Primakoff reactions at lowest four-momentum transfers. Using these processes, the polarizability of the pion, the radiative width of the a2 (1320) and, for the first time, that of the π2 (1670) have been measured. |
