We propose a novel approach to compute the cross section of near-threshold and production in electron-proton scattering at large photon virtualities based on an operator product expansion. We show that the process can be used to extract the gluon part of the D-term gravitational form factor of the proton. At the subleading level, it is also sensitive to the trace anomaly effect of QCD.
