Measurement of thep¯ptotal cross section at √s=1.8 TeV

Abstract
We have measured the antiproton-proton total cross section at √s =1.8 TeV at the Fermilab Tevatron Collider; the value obtained is 78.3±5.9 mb. B, the nuclear slope parameter for elastic scattering, was measured to be 16.3±0.5 (GeV/c)2. From these data, we derive a value for the total elastic cross section.
