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 π ± , K ± , protons and antiprotons, produced in the central region (0.02 ≤ x F ≤ 0.10 and 0.7 ≤ p T ≤ 3.4 GeV/c). Asymmetries for π ± , K ± andp show within measurement errors the linear dependence on x T and change a sign near 0.37. For protons negative asymmetry, independent of x T has been found. The
