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.

Invariant cross sections for hadron production (π±,K±,p and$\bar p$) by protons off C, Al, Cu, Sn and Pb nuclei have been measured at 70 GeV for theP∧ range from 1 up to 4.65 GeV/c. TheA-dependence of the invariant cross section is not described by the exponentialAα(P∧), which points to the presence of secondary hadron absorption in nuclei.

Single-spin asymmetries for hadrons have been measured in collisions of transversely-polarized 40 GeV/c proton beam with an unpolarized liquid hydrogen target. The asymmetries were measured for pi+-, K+-, protons and antiprotons, produced in the central region (0.02 < Xf < 0.10 and 0.7 < Pt < 3.4 GeV/c). Asymmetries for pi+-, K+- and antiprotons show within measurement errors the linear dependence on Xt and change a sign near 0.37. For protons negative asymmetry, independent of Xt has been found. The results are compared with those of other experiments and SU(6) model predictions.

The cross sections for π ± , K ± , p, and p production in pp collisions have been measured at transverse momenta from 0.48 up to 2.21 GeV/ c at 70 GeV. The data are compared with results obtained at lower and higher proton energies and also with the quantum chromodynamics parton model (QPM) calculations. Common behaviour of the cross sections of the form g(p ⊥ )⨍(x ⊥ ) in the energy range above 200 GeV does not take place at lower energies. Qualitatively QPM fits the data and the best agreement is for π + / π − and K + / π + ratios.

Pion - deuteron elastic scattering at large angles from 0.90-GeV/c to 2.025-GeV/c

The differential cross section for the backward (120° ⩽ θ c.m.s. ⩽ 180°) pion-deuteron elastic scattering was measured at eight incident pion momenta from 0.90 to 2.025 GeV/ c . A distinctive change in the shape of the angular distribution is observed. At 0.9 GeV/ c the differential cross section decreases smoothly to 180° in accordance with predictions of multiple-scattering theory. At 1.31 GeV/ c , i.e. in the region of the hypothetical 1 I 6 dibaryon with a mass of 2.9 GeV, the differential cross section is practically independent of angle. At higher energies a sharp backward peak is clearly seen. Connections of our results with dibaryons and Regge asymptotic behaviour are discussed.
