用初态辐射事件测量e+e- -> K+K-eta，K+ K-pi0和KsK +pi-截面
Measurements of e+e- -> K+K-eta, K+K-pi0 and KsK+pi- Cross Sections Using Initial State Radiation Events
摘要：
本文报道了对下列过程的测量：e+e- -> gamma KsK+pi-，e+e- -> gamma K+ K-pi 0，e+e- -> gamma phi eta，e+e- -> gamma phi pi 0。辐射光子的初始状态允许覆盖强子末态的能量范围从阈值到~4.6 GeV。分析的数据样本的总体大小为232 fb-1，由在PEP-II e+e-储存环上运行的BaBar探测器收集。通过对KsK+ π末态的Dalitz图分析，确定了e+e-> KK *（892）截面的等差线和等矢量分量的模量和相对相位。还测量了φ和ρ递归的参数，使用全局拟合程序，该程序利用e+e-> KsK+pi-，K+ K-pi 0，φ eta最终状态的振幅，模量和相位之间的互连。还测量了OZI禁戒过程e+e- -> phi pi 0的截面和J/psi分支分数K_K ~*（892）和K+ K_η。
英文摘要：
This paper reports measurements of processes: e+e- -> gamma KsK+pi-, e+e- -> gamma K+K-pi0, e+e- -> gamma phi eta, and e+e- -> gamma phi pi0. The initial state radiated photon allows to cover the hadronic final state in the energy range from thresholds up to ~4.6 GeV. The overall size of the data sample analyzed is 232 fb-1, collected by the BaBar detector running at the PEP-II e+e- storage ring. From the Dalitz plot analysis of the KsK+pi- final state, moduli and relative phase of the isoscalar and the isovector components of the e+e- -> K K*(892) cross section are determined. Parameters of phi and rho recurrences are also measured, using a global fitting procedure which exploits the interconnection among amplitudes, moduli and phases of the e+e- -> KsK+pi-, K+K-pi0, phi eta final states. The cross section for the OZI-forbidden process e+e- -> phi pi0, and the J/psi branching fractions to KK*(892) and K+K-eta are also measured.
