Description
COMPASS is a multi-purpose experiment operated at CERN for investigations of the strong interaction from low to highest energy scales. At low energies, photon-pion interactions provide input for understanding the effective dynamics of strongly bound states of quarks and gluons, mostly prominently the recent measurement of the polarisability of the charged pion. At higher
energies, the meson resonance spectrum comes into play. COMPASS investigates the coupling of photons to such resonances, which
is described by their radiative widths.
