Abstract We confront predictions for hybrid charmonium and other gluonic excitations in the charm region with recently observed structures in the mass range above 3 GeV. The Y ( 4260 ) , if resonant, is found to agree with expectations for hybrid charmonium. The possibility that other gluonic excitations may be influencing the data in this region is discussed.

• The XYZ states: Experimental and theoretical status and perspectives (2019, background): “Thus, the Y(4230) could be a hybrid charmonium with a spin 1 [186, 190] or spin 0 [187, 464] cc̄ core, or a mixture of both.”
• The Exotic XYZ Charmonium-Like Mesons (2008, background): “the dominant hybrid-charmonium open-charm decay modes are expected to be a meson pair with an S-wave (D, D, Ds, D ∗ s) and a P -wave (DJ , DsJ) in the final state (110).”
• Nonstandard heavy mesons and baryons: Experimental evidence (2017, background): “most strongly promoted as a candidate for a cc̄-gluon charmonium hybrid is the 1−− Y (4260) (302; 303; 304).”

• Heavy-quark QCD exotica (2016, background): “Finally, Close and Page noted that the relatively large width, Γ[Y (4260)] = 120(12) MeV, implies that decays to D1D̄, D′1D̄, and D0D̄ ∗ should be accessible.”
• Exotics: Heavy pentaquarks and tetraquarks (2017, background): “Very much along the same lines, but much earlier, a hybrid interpretation was advanced for the J = 1−− state Y (4260), which has a small e+e− annihilation cross section [51, 312, 313].”
• Hadronic molecules (2017, background): “It is still believed to be a prime candidate, e.g., for a hybrid state (Close and Page, 2005) (for a recent discussion see Ref.”
