In this study, using the data sets taken at center-of-mass energies above 4 GeV by the BESIII detector at the BEPCII storage ring, we search for the reaction e⁺e⁻ → γISRX(3872) → γISRπ+π-J/ψ via the Initial State Radiation technique. The production of a resonance with quantum numbers JPC=1++ such as the X(3872) via single photon e⁺e⁻ annihilation is forbidden, but is allowed by a next-to-leading order box diagram.
