| Research Abstract |
Experimental and theoetical studies on the newly predicted high-density kaonic nuclear systems were advanced. In accordance with the theoretical prediction we analyzed old experimental data of DISTO on the pp->Lambda +p+K+ reaction, which revealed a strong peak due to K-pp with a binding energy around 100 MeV. Extensive Faddeev-Yakubovsky calculations were carried out on K-pp, K-K-pp, etc by varying the strength of the Kbar-N interaction. The observed binding energy of K-pp, a factor of 2 larger than the standard theoretical value, is understood in terms of chiral symmetry restoration effect in dense nuclei. We predicted and calculated the production cross section of the double kaonic nuclei, K-K-pp in high-energy pp collisions.
