关键词: D0-D0混合, 对撞机实验, 本底研究
Abstract: In the asymmetrical e+e- collider experiment at Belle, a sensitive measurement of D0-D0 mixing parameters can be obtained from a time dependent Dalitz analysis of D0→K0sπ+π- decay channel. The related event selection and background studies were discussed, and all the distribution functions of signal and backgrounds were given.
Key words: D0-D0 mixing, e+e- collider experiment, background study
