The elastic and inelastic$\bar p$p cross sections at 70 GeV/c have been determined in an experiment performed at CERN using BEBC equipped with a TST. The topological cross sections were measured and the moments of the inelastic multiplicity distribution are 〈nc〉=6.16±0.09, 〈nc〉/D=2.04±0.05 andf2cc=2.97±0.03. The average number of Dalitz pairs per inelastic event is (3.12±0.09)×10−2. Assuming that these all arise from π0 decay the average π0 multiplicity is$\langle n_{\pi ^0 } \rangle= 2.71 \pm 0.14$. The$\bar p$p−pp cross section differences lead to an annihilation cross section σA = 4.42±0.41 mb and the moments of the annihilation multiplicty distribution are 〈nA〉=8.0±0.3, 〈nA〉/D=2.5±0.2 andf2A−−=−1.4±0.3. An independent check of σA was made by investigating fast forward charged and neutral secondary interactions in the TST and in the surrounding neon-hydrogen mixture, and gives a value σA = 5.0±1.6 mb. The ratio of fast$\bar n$ to$\bar p$ production in non-annihilation interactions at 70 GeV/c is found to be 0.45±0.11.

PAIR PRODUCTION OF PIONS WITH SYMMETRIC MOMENTA IN THE RANGE 0.5-GeV/c <= P(T) <= 2.0-GeV/c in 70-GeV p p COLLISIONS

Phys.Lett.B 112 (1982) 170-172, 1982.

Inspire Record 169450 DOI 10.17182/hepdata.41219

The invariant cross-section slope of the pp→ π + π − +X process as a function of p T is found to have a break near 1 GeV/ c . Fitting the cross section by a sum of two exponents gives the values of powers (12.3±0.9)(GeV/ c ) −1 and (8.7±0.6)(GeV/ c ) −1 . The experimental points at p T ⩾1 GeV/ c are significantly higher than predictions based on hard scattering models such as QCD and CIM.
