Description

BESIII collected about 70 pb-1 e+e- annihilation data around the nominal mass of psi(3770), based on which we present preliminary results of study on the production line-shape of e+e- -> DDbar. In this study, we take into account the effect of interference due to the non-reconant DDbar production to describe the observed anomalous line-shape.
