B0 -> K+ pi-pi0衰变的振幅分析

Amplitude Analysis of the Decay B0 -> K+pi-pi0

The BABAR Collaboration, B. Aubert

摘要:

本文报道了中性B介子到K+ pi-pi 0的无粲强子衰变的振幅分析。利用位于SLAC的PEP-II非对称能量B工厂的BABAR探测器收集的4.54亿个Uppermont(4S)-> B 0 B 0 bar衰变样本,我们测量了B 0和B 0 bar衰变的中间共振和非共振振幅的幅度和相位,并确定了相应的CP平均拟合分数和电荷不对称性。

英文摘要:

We report an updated amplitude analysis of the charmless hadronic decays of neutral B mesons to K+pi-pi0. With a sample of 454 million Upsilon(4S) -> B0B0bar decays collected by the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC, we measure the magnitudes and phases of the intermediate resonant and nonresonant amplitudes for B0 and B0bar decays and determine the corresponding CP-averaged fit fractions and charge asymmetries.
