N2 - We report a measurement of the cross section for the process e+e-→π+π-J/ψ around the X(3872) mass in search for the direct formation of e+e-→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)→π+π-J/ψ is determined to be Γee×B(X(3872)→π+π-J/ψ)
