F. Abe et al., MEASUREMENT OF THE ANTIPROTON-PROTON TOTAL CROSS-SECTION AT ROOT-S=546 AND 1800 GEV, Physical review. D. Particles and fields, 50(9), 1994, pp. 5550-5561
We report a measurement of the proton-antiproton total cross section s
igma(T) at c.m.s. energies root s = 546 and 1800 GeV. Using the lumino
sity-independent method, we find sigma(T) = 61.26 +/- 0.93 mb at root
s = 546 GeV and 80.03 +/- 2.24 mb at root s = 1800 GeV. In this energy
range, the ratio sigma(el)/sigma(T) increases from 0.210 +/- 0.002 to
0.246 +/- 0.004.
