Strange Tribaryons as Nona-quark States (2004)
Maezawa, Yuu, Hatsuda, Tetsuo, Sasaki, Shoichi
Strange tribaryons as nona-quark (9 quark) states is studied to describe the S=-1 resonance S^0(3115) recently discovered in the reaction K- + ^4 He -> S^0 + p. We have identified S^0(3115) as a...
Wandering in Color-Space -- why the life of pentaquark is so long ? -- (2004)
Maezawa, Yuu, Maruyama, Toshiki, Itagaki, Naoyuki, Hatsuda, Tetsuo
The problem of the long life time of the pentaquark $\Theta^+$ is investigated on the basis of the color molecular dynamics simulation. We find that it takes a long time (typically of 50-100 fm/c)...
