Evidence is reported for a narrow structure near the J/ψϕ threshold in exclusive B+→J/ψϕK+ decays produced in p̅ p collisions at sqrt[s]=1.96 TeV. A signal of 14 ± 5 events, with statistical significance in excess of 3.8 standard deviations, is observed in a data sample corresponding to an integrated luminosity of 2.7 fb-1, collected by the CDF II detector. The mass and natural width of the structure are measured to be 4143.0 ± 2.9(stat) ± 1.2(syst) MeV/c2 and 11.7-5.0+8.3(stat) ± 3.7(syst) MeV/c2.
