Abstract
We report the results of a search for the X(1835) state in the process e+e-→J/ψX(1835) using a data sample of 672 fb-1 collected with the Belle detector at and near the Ï (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+e-→J/ψX(1835))·B(X(1835)→≥3 charged tracks)<1.3 fb at 90% confidence level. © 2014 American Physical Society.
