Search for the process $e^{+}{e}^{-}\to J/\psi +X(1835)$ at $\sqrt{s}\approx 10.6$GeV

Abstract

We report the results of a search for the $X(1835)$ state in the process $e^{+}{e}^{-}\to J/\psi +X(1835)$ using a data sample of 672 fb${}^{-1}$ collected with the Belle detector at and near the ${\rm Y}(4S)$ resonance at the KEKB asymmetric-energy $e^{+}{e}^{-}$ collider. No significant evidence is found for this process, and an upper limit is set on its cross section times the branching fraction: ${\sigma }_{\mathrm{Born}}(e^{+}{e}^{-}\to J/\psi X(1835))\cdot$ {$\mathcal{B}(X(1835)\to \ge 3$ charged tracks)} $<1.3\mathrm{fb}$ at 90% confidence level.
