Research Abstract |
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.
