Observation of the Narrow State $X(3872)\to J/\psi {\pi }^{+}{\pi }^{-}$ in $\bar{p}p$ Collisions at $\sqrt{s}=1.96 \TeV$

Abstract

We report the observation of a narrow state decaying into $J/\psi {\pi }^{+}{\pi }^{-}$ and produced in $220p{b}^{-1}$ of $\bar{p}p$ collisions at $\sqrt{s}=1.96TeV$ in the CDF II experiment. We observe $730\pm 90$ decays. The mass is measured to be $3871.3\pm 0.7(stat)\pm 0.4(syst)MeV/c2$, 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.
