Abstract

We report the results of a search for a charmoniumlike state produced in the process γγ→ωJ/ψ in the 3.9-4.2GeV/c2 mass region. We observe a significant enhancement, which is well described by a resonant shape with mass M=(3915±3±2)MeV/c2 and total width Γ=(17±10±3)MeV. This enhancement may be related to one or more of the three charmoniumlike states so far reported in the 3.90-3.95GeV/c2 mass region.
