First results on low momentum transfer elastic scattering at the CERN proton-antiproton collider

Proton-antiproton elastic scattering at a centre-of-mass energy of 540 GeV was measured in the four-momentum transfer range 0.05 < − t < s.19 GeV 2. The t-distribution can be fitted by the exponential exp( b) with b=17.2±1.0 GeV −2. This result indicates a rapid decrease of the width of the di...

Zusammenfassung:Proton-antiproton elastic scattering at a centre-of-mass energy of 540 GeV was measured in the four-momentum transfer range 0.05 < − t < s.19 GeV 2. The t-distribution can be fitted by the exponential exp( b) with b=17.2±1.0 GeV −2. This result indicates a rapid decrease of the width of the diffraction peak between ISR and Collider energies.
