Original language description
The COMPASS Collaboration at CERN has investigated the reaction ?-?->?-?-?+ embedded in the Primakoff reaction of 190 GeV pions scattering in the Coulomb field of a lead target, ?-Pb->?-?-?+Pb . Exchange of quasi-real photons is selected by isolating thesharp Coulomb peak observed at momentum transfer below 0.001 (GeV/c)2. Using a partial-wave analysis the amplitudes and relative phases of the a2(1320) and ?2(1670) mesons have been extracted, and the Coulomb and the diffractive contributions have beendisentangled.
