Popis: | A transformation table between physical bases including hidden color channels and symmetry bases for nonstrange six-quark systems is provided by using fractional parentage expansion method. By solving a coupled-channel equation, in the framework of the resonating group method (RGM), the effect of hidden color channels to all nonstrange six-quark systems is examined. It is shown that the overall effects from hidden color channels would reduce the energies of systems. For ΔΔ systems, the greatest decrease is about 20 MeV. Effects of hidden color on the masses of NN systems have been found to be about 1 MeV. However, we should emphasize that such a minor change for NN system is not negligible. We also give the most favorable hidden color channels for NN system. |
