Abstract
Based on 7.33 fb−1 of e+e− collision data taken at center-of-mass energies between 4.128 and 4.226 GeV with the BESIII detector, we measure the branching fraction of Ds*+--> D+π0 relative to that of Ds*+ -->D+γ to be (6.16 pm 0.43 pm 0.18)%. The first uncertainty is statistical and the second one is systematic. By using the world average value of the branching fraction of Ds*+--> D+e+e−, we determine ss the branching fractions of Ds*+--> D+γ and Ds*+--> D+π0 to be (93.57 0.38 0.22Þ% and (5.76 0.38 0.16Þ%, respectively.File in questo prodotto:
