用初态辐射测量e+e-> D0D *-pi+截面

Measurement of the e+e- --> D0D*-pi+ cross section using initial-state radiation

Belle Collaboration, G. Pakhlova

摘要:

我们报告的独家截面的测量e+e-> D 0 D *-π +作为质心能量的函数从D 0 D *-π +阈值到5.2 GeV的初始状态辐射。没有发现Y(4260)→> D 0 D *-π +衰变的证据。该分析是基于在KEKB非对称能量e+e-对撞机上Belle探测器在10.58 GeV质心能量处或附近收集的数据样本,积分亮度为695 1/fb。

英文摘要:

We report measurements of the exclusive cross section for e+e- --> D0D*-pi+ as function of center-of-mass energy from the D0D*-pi+ threshold to 5.2 GeV with initial-state radiation. No evidence is found for Y(4260)-->D0D*-pi+ decays. The analysis is based on a data sample collected with the Belle detector at or near a center-of-mass energy of 10.58 GeV with an integrated luminosity of 695 1/fb at the KEKB asymmetric-energy e+e- collider.
