Aa. Volkov et al., ANGULAR-DISTRIBUTION OF THE PRODUCTION OF SYMMETRICAL HADRON PAIRS INPI-P-COLLISIONS AT 40 GEV, JETP letters, 58(7), 1993, pp. 486-492
The angular distribution o the cross sections for the production of sy
mmetric hadron pairs with effective masses from 2.4 to 5.4 GeV/c2 at s
quare-root s=8.7 GeV has been measured on a two-arm spectrometer. The
experimental data are compared with theoretical predictions of a model
based on QCD.
