We measured the cross sections of hadron pair production (π, K, p) with symmetric momenta produced back-to-back in the c.m.s. in pp collisions in the range 0.45 ⩽ P T ⩽ 1.99 GeV/ c . Particle correlations showing dependence on quantum numbers and transverse momentum are presented. The data are discussed in the framework of parton models.

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

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.
