| 英文摘要 | We report measurements of the line shapes of D+D-, D-0(D) over bar (0) and D (D) over bar production as well as the line shape of the ratio of the production rates of D+D- and D-0(D) over bar (0) in e(+)e(-) annihilation at psi(3770) resonance. We find that the line shapes of D+D-, D-0(D) over bar (0) and D (D) over bar production are similar to an anomalous line shape of cross sections for e(+)e(-) -> hadrons observed in the center-of-mass energy range from 3.70 to 3.87 GeV.
