Abstract: (APS)

We report the results of a search for the X(1835) state in the process e+eJ/ψX(1835) using a data sample of 672fb1 collected with the Belle detector at and near the ϒ(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: σBorn(e+eJ/ψX(1835))·B(X(1835)3charged tracks)<1.3fb at 90% confidence level.
