We measured the total cross section for p-pbar scattering at sqrt(s) = 52.8 GeV at the CERN ISR, using the direct, total-rate method. The result obtained, σ_tot(ppbar) = 44.70 ± 0.53 mb, shows that, in common with σ_tot(pp), this cross section also starts to rise in the ISR energy range. We remeasured the total cross section for pp scattering at the same energy, obtaining σ_tot(pp) = 43.26 ± 0.33 mb, and found for the difference a value of 1.44±0.45 mb.

Abstract
We measured the total cross section for p-pbar scattering at sqrt(s) = 52.8 GeV at the CERN ISR, using the direct, total-rate method. The result obtained, σ_tot(ppbar) = 44.70 ± 0.53 mb, shows that, in common with σ_tot(pp), this cross section also starts to rise in the ISR energy range. We remeasured the total cross section for pp scattering at the same energy, obtaining σ_tot(pp) = 43.26 ± 0.33 mb, and found for the difference a value of 1.44±0.45 mb.File in questo prodotto:
