我们报告了在从\(D^{0}\pi^{+}\)阈值到\(5.2\)GeV的质心能量范围内，具有初态辐射的\(e^{+}e^{-}\to D^{0}\overline{D}^{* +}\pi^{-}\)的遍举截面测量结果。没有发现\(Y(4260)\to D^{0}\overline{D}^{* +}\pi^{-}\)衰变的证据。该分析基于在KEKB非对称能量\(e^{+}e^{-}\)对撞机上，质心能量为\(10.58\)GeV或其附近，由Belle探测器收集的积分亮度为\(695 fb^{-1}\)的数据样本。
We report measurements of the exclusive cross section for e(+)e(-)->(DD*-)-D-0 pi(+) as a function of center-of-mass energy from the (DD*-)-D-0 pi(+) threshold to 5.2 GeV with initial-state radiation. No evidence is found for Y(4260)->(DD*-)-D-0 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 fb(-1) at the KEKB asymmetric-energy e(+)e(-) collider.
