Inclusive Neutral Particle Production in Anti Pp Interactions at 22.4 GeV/C. Part 2. Differential Distributions. Study of the lambda Polarization

摘要

The differential distributions over longitudinal and transverse Feynman variables for inclusive gamma , K/sub s/ exp 0 , lambda production in anti pp interactions at 22.4 GeV/c are presented. The rapidity distributions in the c.m.s. for gamma and K exp 0 /K exp 0 -tilde particles are well described by the quark-antiquark fusion model. In the central region there is some evidence for scaling behavior of the invariant differential cross sections F for the anti pp implies gamma +all in the range from 22.4 GeV/c to 100 GeV/c, while for the K exp 0 / K exp 0 tilde production F rises in this energy interval. A non-zero lambda polarization of -0.414+-0.206 was measured. (Atomindex citation 10:475657)
