We propose a new reaction mechanism for the study of strange and charmed baryon productions. In this mechanism we consider the correlation of two quarks in baryons, so it can be called the two-quark process. As in the previously studied one-quark process, we find large production rates for charmed baryons in comparison with strange baryons. Moreover, the new mechanism causes the excitation of both the $\rho$ mode and the $\lambda$ mode. Using the wave functions for baryons from a quark model, we compute the production rates of various baryon states. We find that the production rates reflect the structure of the wave functions that imply the usefulness of the reactions for the study of baryon structures.

具有瞬时相互作用的重重子产生

我们提出了一种新的反应机制来研究奇怪和迷人的重子产物。在这个机制中,我们考虑了重子中两个夸克的相关性,因此可以称为二夸克过程。与之前研究的一夸克过程一样,我们发现与奇异重子相比,迷住重子的生产率更高。此外,新机制导致 $\rho$ 模式和 $\lambda$ 模式的激发。使用夸克模型中重子的波函数,我们计算各种重子态的产生率。我们发现生产率反映了波函数的结构,这意味着反应对研究重子结构的有用性。
