Multi-quark states

Abstract

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$\Omega$ dibaryon has been shown to have a width as small as 12-22 keV and should be detectable in $\Omega$ high productivity reactions such as at RHIC, COMPAS and the planned JHF and FAIR projects.
