| 英文摘要 | The continuum one-photon annihilation at psi(2S) in e(+)e(-) experiment is studied. Such contributions to the measured final states omegapi(0) and pi(+)pi(-) at psi(2S) mass are estimated by phenomenological models. It is found that these contributions must be taken into account in the determination of branching ratios of psi(2S)-->omegapi(0) and psi(2S)-->pi(+)pi(-), as well as other electromagnetic decay modes. The study reaches the conclusion that in order to obtain the correct branching ratios on these decay modes at BES, at least 10pb(-1) of data below the psi(2S) peak is needed. |
