Color Scheme

The problem of long range forces between hadrons is re-examined. Without color degrees of freedom the confining potentials lead to unacceptably large van der Waals forces. The color degrees of freedom are investigated in the case of mesons taking into account both of the color singlet states of four constituents. The consistency of the color scheme requires the existence of four-quark bound states as well as two separate mesons and puts still restrictions on the confining potentials.

AbstractThe spectrum of $$\varLambda $$ Λ and $$\varSigma $$ Σ excitations is reviewed taking into account (nearly) all hyperon resonances which were seen in early analyses or in one of the recent partial-wave analyses. The spectrum is compared with the old Isgur–Karl model and the Bonn model. These models allows us to discuss the SU(3) structure of the observed resonances. The SU(3) decomposition is compared with SU(6) relations between the different decay modes. Seven $$\varLambda $$ Λ states are proposed to be classified as SU(3) singlet states. The hyperon spectrum is compared with the spectrum of N and $$\varDelta $$ Δ resonances.
