Résumé
A precise measurement of {Mathematical expression} elastic scattering in the Coulomb strong-interaction interference region was performed at the CERN {Mathematical expression} Collider at a centre-of-mass energy of 541 GeV. The ratio of the real-to-imaginary part of the forward elastic-scattering amplitude was found to be ρ=0.135±0.015. The slope of the exponential fall-off of the strong-interaction part was also measured to be b=15.5±0.1 GeV-2. Using this new result, an overall fit to the data on the total cross-section and on the real part for {Mathematical expression} and pp was performed using dispersion relations. Numerical predictions are presented for total cross-sections at LHC and SSC energies.
