Charmonium States

IfX(3872)is described by the picture as a mixture of the charmonium and molecularD*Dstates;Y(3940)as a mixture of theχc0andD*D*states; andY(4260)as a mixture of the tetraquark and charmonium states, their orthogonal combinations should also exist. We estimate the mass and residues of the states within the QCD sum rules method. We find that the mass splitting amongX, Yand their orthogonal states is at most 200 MeV. Experimental search of these new states can play critical role for establishing the nature of the new charmonium states.
