[K-ppn]束缚态的研究进展
Critical review of [K- ppn] bound states
摘要：
我们做了一个深入的研究过程中的三体K介子吸收的核，在最近的FINUDA实验，声称存在一个深绑定的K介子态从观察的峰值在Lambda d不变的质量分布以下的K-吸收Li 6。我们发现，该峰自然地解释在K-吸收从三个核子离开观众的休息。我们还可以重现在同一实验中测量的所有其他可观测量，并用于支持深度束缚K介子态的假设。我们的研究还揭示了有趣的方面K介子吸收的核，一个过程，必须理解，以便在寻找K-深束缚态的核中取得进展。
英文摘要：
We make a thorough study of the process of three body kaon absorption in nuclei, in connection with a recent FINUDA experiment which claims the existence of a deeply bound kaonic state from the observation of a peak in the Lambda d invariant mass distribution following K- absorption on Li6. We show that the peak is naturally explained in terms of K- absorption from three nucleons leaving the rest as spectators. We can also reproduce all the other observables measured in the same experiment and used to support the hypothesis of the deeply bound kaon state. Our study also reveals interesting aspects of kaon absorption in nuclei, a process that must be understood in order to make progress in the search for K- deeply bound states in nuclei.
