The observation of the Y (4140) structure in B± → J/ΨφK± decays produced in pp collisions at √ s = 1.96 TeV is reported with a statistical significance greater than 5 standard deviations. A fit to the J/Ψφ mass spectrum is performed assuming the presence of a Breit-Wigner resonance. The fit yields a signal of 19 ± 6 (stat) ± 3 (syst) resonance events, and resonance mass and width of 4143.4+2.9 -3.0 (stat)±0.6 (syst) MeV/c2 and 15.3+10.4 -6.1 (stat)±2.5 (syst) MeV/c2, respectively. The parameters of this resonancelike structure are consistent with values reported from an earlier CDF analysis.
