N2 - The recent observation of a hadronic resonance d* in the proton-neutron system with isospin I=0 and spin-parity JP=3+ raises the possibility of producing other novel six-quark dibaryon configurations allowed by QCD. A dramatic example of an exotic six-quark color-singlet system is the charge Q=+4, isospin I=3, Iz=+3 |uuuuuu〉 state which couples strongly to δ+++δ++. The width and decay properties of such six-quark resonances could be regarded as manifestations of "hidden-color" six-quark configurations, a first-principle prediction of QCD - SU(3)-color gauge theory for the deuteron distribution amplitude. Other implications and possible future experiments are discussed.
