Phys. Rev. Lett. 62, 1821–1824 (1989)Measurement of the branching fractions for D0→π-e+νe and D0→K-e+νe and determination of ‖Vcd/Vcs‖2Received 30 December 1988; published in the issue dated 17 April 1989 Measurements of the exclusive branching fractions B(D0→π-e+νe) and B(D0→K-e+νe), using data collected at the ψ(3770) with the Mark III detector at the SLAC e+e- storage ring SPEAR, are used to determine the ratio of the Kobayashi-Maskawa matrix elements ‖Vcd/Vcs‖2 =0.057±0.015+0.038±0.005. © 1989 The American Physical Society URL:
