摘要:

从强相互作用的基本理论QCD出发,直接研究了重子-重子之间的奇异$S=-2$相互作用。HAL QCD方法使我们能够在不使用任何实验信息的情况下从Nambu-Bethe-Salpeter波函数中提取重子相互作用。本文给出了我们在K计算机上得到的具有大格点体积的$S = -2$的(几乎)物理点规范组态所计算的势,并利用这些势讨论了H-重子态.

英文摘要:

The strangeness $S=-2$ baryon-baryon interaction is investigated directly from the fundamental theory of the strong interaction, QCD. The HAL QCD method enables us to extract baryon interactions from the Nambu-Bethe-Salpeter wave functions without using any experimental information. We present our latest result on the $S = -2$ baryon interactions and discuss the H-dibaryon state using potentials which are calculated by using the (almost) physical point gauge configurations with large lattice volume of$(8.1{\rm{fm}})^4$ generated on the K-computer.
