摘要
The pentaquark state recently discovered has been discussed based on various quark model calculations. Odd parity for the state can not be ruled out theoretically because contributions related to non-trivial color structures have not been studied completely. Other multiquark states, especially dibaryons, have been discussed also. A strangeness -3 N dibaryon has been shown to have a width as small as 12-22 keV and should be detectable in high productivity reactions such as at RHIC, COMPAS and the planned JHF and FAIR projects.
