Abstract We give a brief discussion on the measurement of the cross section for DD production around the ψ(3770) resonance, and point out a new calculation of the cross sections based on the absolute measurements. Compared with single tag and double tag analyses, the new calculation provides us with many more opportunities to perform the cross section measurement.
