Abstract
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.
