超子产生的COSY-11测量综述

Summary of the COSY-11 Measurements of Hyperon Production

D. Grzonka

摘要:

综述了COSY-11超子产生的研究进展。显示了在反应通道pp->pK+Lambda、pp->pK+ Sigma 0和pp->nK+Sigma+中的实验结果。从阈值到约90 MeV的过剩能量的激发函数已被评估与高精度的λ和Σ 0生产。提取了Lambdap和Sigma 0 p终态相互作用。在13和60 MeV过剩能量下测量了Sigma+的产生。

英文摘要:

The studies of hyperon production performed at COSY-11 are summarized. The results of the experiments in the reaction channels pp-->pK+Lambda, pp-->pK+Sigma0, and pp-->nK+Sigma+ are shown. Excitation functions fromthreshold up to about 90MeV excess energies have been evaluated with high precision for the Lambda and Sigma0 production. The Lambdap and Sigma0p final state interactions were extracted. The Sigma+ production was measured at 13 and 60 MeV excess energies.
