Measurement of the \(e^+e^-\to\pi^+\pi^-J/\psi\) cross section in the vicinity of 3.872 GeV
We report a measurement of the cross section for the process \(e^+e^-\to\pi^+\pi^-J/\psi\) around the \(X(3872)\) mass in search for the direct formation of \(e^+e^-\to X(3872)\) through the two-photon fusion process. No enhancement of the cross section is observed at the \(X(3872)\) peak and an upp...

a measurement of the cross section for the process \(e^+e^-\to\pi^+\pi^-J/\psi\) around the \(X(3872)\) mass in search for the direct formation of \(e^+e^-\to X(3872)\) through the two-photon fusion process. No enhancement of the cross section is observed at the \(X(3872)\) peak and an upper limit on the product of electronic width and branching fraction of \(X(3872)\to\pi^+\pi^-J/\psi\) is determined to be \(\Gamma_{ee}\times\mathcal{B}(X(3872)\to\pi^+\pi^-J/\psi)<7.5\times10^{-3}\,\text{eV}\) at \(90\,\%\) confidence level under an assumption of total width of \(1.19\pm0.21\) MeV. This is an improvement of a factor of about \(17\) compared to the previous limit. Furthermore, using the latest result of \(\mathcal{B}(X(3872)\to\pi^+\pi^-J/\psi)\), an upper limit on the electronic width \(\Gamma_{ee}\) of \(X(3872)\) is obtained to be \(<0.32\,\text{eV}\) at the \(90\,\%\) confidence level.</abstract><cop>Ithaca</cop><pub>Cornell University Library, arXiv.org</pub><oa>free_for_read</oa></addata></record> |
