Production of charged hadrons with large transverse momenta in pp collisions at 70 GeV

The invariant cross sections for production of ..pi../sup + -/, K/sup + -/, p, and p-bar and the ratios of particle yields in the transverse momentum range of 1.0 to 4.1 GeV/c at 90/sup 0/ angle in the c.m.s. were measured. The dependences of the cross sections and of the meson-yield ratios on energy and on X/sub perpendicular/ = 2P/sub perpendicular//..sqrt..s are described qualitatively by the model based on quantum chromodynamics.
