Abstract
A super-hypernucleus is a nucleus which consists of many strange quarks as well as up and down quarks. An important part of the results of our recent investigation on the mass spectrum and other properties of super-hypernuclei in the quark-shell model is reported. It is expected that not only certain exotic nuclei such as the “dideltas” (Dδ ++++ and Dδ - ) but also certain super-hypernuclei such as the “hexalambda” (Hλ) and the “vigintiquattuoralambda” (Vqλ) may appear as quasi-stable nuclei. However, in the quark-shell model, there is no qualitative reason why the “dihyperon” or “H dibaryon” (H) should be quasi-stable or even stable. Many other predictions including a sudden increase of the K/π ratio due to the production of super-hypernuclei in heavy-ion collisions at high energies are also made.
