New approach toward ultra-high density quark-matter via K-bar meson bound-state

物质质量的起源可以用强子质量来粗略地解释。然而，强子质量本身仍然是个谜。它由三个夸克组成，但质量之和只有强子的1%。另一方面，K-巴介子的强吸引性也意味着核物质的自发核密度变化，这可能会影响目前质量形成方案中的介质质量。因此，目前的研究主要集中在核介质中K-巴介子的质量修正。

The origin of the matter mass can be roughly explained by the hadron mass. However, the hadron mass itself is still mysterious. It consists of three quarks, but the sum of the masses is only 1% of the hadron. On the other hand, the strongly attractive nature of K-bar meson also implies spontaneous nuclear density change of the nuclear matter, which can affect the mass in the media in the present mass formation scenario. Thus, present research focuses on the mass modification of K-bar meson in nuclear media.
