標題: | Evidence for B0→χc1π0 at Belle | 作者: | WEI-SHU HOU YEE HSIUNG Kumar, R. |
公開日期: | 2008 | 卷: | 78 | 期: | 091104 | 起(迄)頁: | - | 來源出版物: | Physical Review D - Particles, Fields, Gravitation and Cosmology | 摘要: | We present a measurement of the branching fraction for the Cabibbo- and color-suppressed B0→χc1π0 decay based on a data sample of 657×106BB̄ events collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We observe a signal of 40±9 events with a significance of 4.7σ including systematic uncertainties. The measured branching fraction is B(B0→χc1π0)=(1. 12±0.25(stat)±0.12(syst.))×10-5. © 2008 The American Physical Society. |
