Symmetric hadron pair production cross section (π+ π+, π+K+, π+p,K+p, andpp) were measured in the range 0.48≦P⊥≦2.29 GeV/c from Be, Cu, and Pb targets bombarded by 70 GeV protons. TheA-dependence exponent as a function ofP⊥ differs for varios pairs.A steep drop of α for meson pairs atP⊥>1.5 GeV/c is observed.

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.
