Evidence for a Narrow Near-Threshold Structure in the $J/\psi \varphi$ Mass Spectrum in $B^{+}\to J/\psi \varphi K^{+}$ Decays

Abstract

Evidence is reported for a narrow structure near the $J/\psi \varphi$ threshold in exclusive $B^{+}\to J/\psi \varphi K^{+}$ decays produced in $\bar{p}p$ collisions at $\sqrt{s}=1.96 \TeV$. A signal of $14\pm 5$ events, with statistical significance in excess of 3.8 standard deviations, is observed in a data sample corresponding to an integrated luminosity of $2.7 \ifb$, collected by the CDF II detector. The mass and natural width of the structure are measured to be $4143.0\pm2.9(\mathrm{stat})\pm1.2(\mathrm{syst}) \MeVcc$ and $11.7^{+8.3}_{-5.0}(\mathrm{stat})\pm3.7(\mathrm{syst}) \MeVcc$.
