Experimental determination of elastic and topological cross sections in 48. 9-GeV/c p-barp interactions

Journal Article · · Phys. Rev., D; (United States)
The elastic and topological p-barp cross sections have been measured at 48.9 GeV/c in the Fermilab proportional-wire-chamber--30-in.-bubble-chamber hybrid spectrometer. The elastic cross section is 7.81 +- 0.24 mb and the slope of the elastic differential cross section at t=0 is 13.4 +- 0.8 GeV/sup -2/. Further, the moments of the inelastic topological-cross-section distribution are =5.69 +- 0.03, /D=2.10 +- 0.02, and f/sup c/c/sub 2/=1.67 +- 0.12.
