| 英文摘要 | Absolute measurement of branching fractions of purely leptonic decay, semi-leptonic decay and phi pi(+) decay of the D-s meson at a c. m. energy of 4.03 GeV were completed from the BES experiment at the BEPC electron-positron collider. The method by using combined confidence level for pion and kaon separation, the D-s single and double lagging technology, and the maximum likelihood functions in the estimate of the D-s branching fractions are described in details. Discussion and comments on these physics results are made. Prospect for improved measurement of D-s physics in future is also given. |
