摘要：

The results obtained by measuring the inclusive distributions of the Feynman variable x (F) and the transversemomentum for the production of K (S) (0) mesons in proton-nucleus interactions at 70 GeV/c for three targets (C, Si, and Pb) are presented. The mass-number (A) dependence of the cross section for K (S) (0) -meson production is studied. The measured value of the exponent alpha in the formula sigma similar to A (alpha) agrees within the errors with its counterpart at higher energies. With the aid of the A dependence, the measured yield of K (S) (0) mesons at x (F) = 0 is compared with the yield of K (+) and K (-) mesons in the proton-proton reaction at 70 GeV/c. The inclusive spectra of longitudinal and transverse variables for K (S) (0) -meson production are contrasted against the predictions of the FRITIOF and UrQMD models.
