Abstract An experimental study was carried out for J / ψ production in a two-photon process using the VENUS detector at the TRISTAN e + e − collider. The study was based on 357 pb −1 data at an average e + e − center-of- massenergy of 58 GeV. No significant signal was observed, and the upper limit of the production cross section was obtained.
