摘要：

Using a soft pion theorem based on chiral symmetry and a Delta(1232) resonance model, we propose an estimate for the production cross section of low energy pions in the deeply virtual Compton scattering (DVCS) process. In particular, we express the ep-->egammapiN processes in terms of generalized parton distributions. We provide estimates of the contamination of the ep-->egammap DVCS observables due to this associated pion production process when the experimental data are not fully exclusive, for a set of kinematical conditions representative of present or planned experiments at JLab, HERMES, and COMPASS.
