Evidence for a Narrow Near-Threshold Structure in the J/ psi phi Mass Spectrum in B+-->J/ psi phi K+ Decays
Evidence is reported for a narrow structure near the J/ψϕ threshold in exclusive B+→J/ψϕK+ decays produced in (p)over-bar p collisions at √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 integr...
