Description

Proton-antiproton elastic scattering was measured at the CERN SPS Collider at the centre-of-mass energy √s = 546 GeV in the Coulomb interference region. The data provide information on the phase of the hadronic amplitude in the forward direction. The conventional analysis gives for the ratio ρ of the real to the imaginary part of the hadronic amplitude the result ρ = 0.24±0.04. (orig.)
