Direct Measurement of Branching Fraction for Inclusive Semimuonic Decay of Neutral D Mesons
-
Abstract
Using a data sample of about 33pb-1 collected at and around √s=3.773GeV with the BES-II detector at the BEPC, we have directly measured the branching fraction for inclusive semimuonic decay of neutral D mesons to be BF(D0→μ+X) =(7.2±1.5±0.8)%.
