Abstract We report the observation of a narrow state decaying into J/ψπ+π− and produced in 220   pb−1 of p̄ p collisions at s√=1.96   TeV in the CDF II experiment. We observe 730±90 decays. The mass is measured to be 3871.3±0.7(stat)±0.4(syst)   MeV/c2, with an observed width consistent with the detector resolution. This is in agreement with the recent observation by the Belle Collaboration of the X(3872) meson.
