摘要: We correct the mistaken claim made by Guzey and Polyakov [Eur. Phys. J. C 46, 151 (2006) ] Teckentrup [Phys. Rev. D 74, 054027 (2006)] that minimal model of dual parametrization nucleon generalized parton distributions gives a good, essentially model-independent description high-energy data on deeply virtual Compton scattering (DVCS). In implementation Guzey-Polyakov Guzey-Teckentrup (see above), numerical prefactor two in front DVCS amplitude was missing. show corrected significantly overestimates Hadron Electron Ring Accelerator (H1 ZEUS experiments) cross section.
