TL;DR: In this paper, the authors observed a resonance in the total cross section for hadron production in e/sup +/e/sup -/ annihilation at a mass of 37772 +- 6 MeV/c/sup 2/ having a total width of 28 +- 5 MeV /c/c 2/ and a partial width to electron pairs of 370 +- 90 eV /e/c /sup 2 /

TL;DR: In this article, the masses of D mesons produced in the decay of the decay psi (3772) and DD-bar were determined to be 1863.9 MeV/c/sup 2/ and 1868.9.
Journal ArticleDOI

TL;DR: In this article, anomalous electron production in multiprong events produced by e/sup +/e/sup -/ annihilation at the psi (3772) was observed and the branching ratio for D decay to an electron plus additional particles, averaged over the neutral and charged D, was found to be (7.2 +- 2.8) %.
