用瞬子相互作用产生重子

Heavy baryon production with an instanton interaction

Sang-In Shim, Atsushi Hosaka, Hyun-Chul Kim

摘要:

我们提出了一种新的反应机制,用于研究奇异和奇异重子的产生。在这个机制中,我们考虑了重子中两个夸克的关联,因此可以称之为双夸克过程。在以前研究的单夸克过程中,我们发现大的生产率相比,奇怪的重子的魅力重子。此外,新的机制导致$ρ$模式和$λ$模式的激发。利用夸克模型中重子的波函数,计算了各种重子态的产生率。我们发现,生产率反映的波函数,这意味着有用的研究重子结构的反应的结构。

英文摘要:

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 $ρ$ mode and the $λ$ 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.
