Measurement of the elastic, total and diffraction cross sections at tevatron energies

The CDF collaboration has measured the differential elastic cross section dσel/dt, the single diffraction dissociation double differential cross section d2σsd/dM2dt and the total inelastic cross section for antiproton-proton collisions at center of mass energies √s = 546 and 1,800 GeV. Data for this measurement have been collected in short dedicated runs during the 1988--1989 data taking period of CDF. The elastic scattering slope is 15.28 ± 0.58 (16.98 ± 0.25) GeV-2 at √s = 546 (1,800) GeV. Using the luminosity independent method (1 + ρ2)σT is measured to be 62.64 ± 0.95 (81.83 ± 2.29) mb at √s = 546 (1,800) GeV. Assuming ρ = 0.15 the elastic, total and single diffraction cross sections are σel = 12.87 ± 0.30, σT = 61.26 ± 0.93 and σsd = 7.89 ± 0.33 mb (σel = 19.70 ± 0.85, σT = 80.03 ± 2.24 and σsd = 9.46 ± 0.44 mb) at √s = 546 (1,800) GeV
