Meson spectroscopy in diffractive dissociation of high‐energetic pions at COMPASS

COMPASS at CERN uses hadron and muon beams with up to 200 GeV∕c momentum, produced from the SPS proton beam, for investigations in hadron structure and spectroscopy. From a pilot run with a 190 GeV∕c pion beam on a lead target, various results are presented. In the region of low momentum transfer, i...

description COMPASS at CERN uses hadron and muon beams with up to 200 GeV∕c momentum, produced from the SPS proton beam, for investigations in hadron structure and spectroscopy. From a pilot run with a 190 GeV∕c pion beam on a lead target, various results are presented. In the region of low momentum transfer, interference of photon‐exchange and strong production of the a1(1260) and a2(1320) resonances is observed, revealing the different nature of the two interactions.
