摘要：
We show that the recent experimental data on the cross section of the process e(+) e(-) -> Lambda(Lambda) over bar near the threshold can be perfectly explained by the final-state interaction of Lambda and Lambda. The enhancement of the cross section is related to the existence of low-energy real or virtual state in the corresponding potential. We present a simple analytical formula that fits the experimental data very well.
