charmonium
charmonium Particle Physics. (tʃɑːˈməʊnɪəm) [f. charm n.1 + -onium 2.] A charmed quark and a charmed antiquark bound to one another.1975 Physical Rev. Lett. XXXIV. 44/1 Another way of seeing that a Coulomb-like picture is not completely correct is to estimate the size of a ‘charmonium’ atom. 1980 Sc... Oxford English Dictionary

Quarkonium
Heavy quarks Examples of quarkonia are the J/ψ meson (the ground state of charmonium, ) and the meson (bottomonium, ). Charmonium In the following table, the same particle can be named with the spectroscopic notation or with its mass. wikipedia.org

-onium
-onium, suffix [abstracted from ammonium.] 1. Chem. Used in forming the names of complex cations that contain a more or less electronegative central atom, usu. bonded to a number of protons (or to other species that are regarded as substituents), as arsonium, carbonium, hydrazonium, nitronium, oxoni...

Y(4260)
It being a Charmonium state is unlikely because the Y(4260) is heavier than the threshold for production of two D mesons, yet sits, surprisingly in a dip wikipedia.org

Sookyung Choi
Choi predicted the X(3872) particle could be a charmonium state or a DD* hadronic molecule. The BES III experiment identified new charmonium states with non-zero electric charge. wikipedia.org

Moss became the spokesperson for the E772 experiment at Fermilab, which involved dimuon production (i.e. of muon pairs via a Drell–Yan process and from charmonium In addition, the E772 science team gained evidence of charmonium and charm formation in nuclei from dimuon generation. wikipedia.org

J/psi meson
The is the most common form of charmonium, due to its spin of 1 and its low rest mass. The name charmonium is used for the and other charm–anticharm bound states. wikipedia.org
