τ-> V P-nu(τ)的更新分析:理论与实验

Update analysis of tau- --> V P- nu(tau): Theory and Experiment

Zhi-Hui Guo

摘要:

在共振手征理论中,我们研究了τ轻子衰变为矢量共振加赝Goldstone介子和τ中微子的过程。讨论了两类过程:(a)tau->(rho pi-,omega pi-,phi pi-,K*0 K-)nu(tau),属于Delta S=0过程;(b)Delta S = 1过程,如tau->(rho K-,omega K-,phi K-,\bar{K*0} pi-)nu(tau).为了拟合τ-> ω π- nu(τ)谱函数和τ-> ω K-nu(τ)的衰减分布,得到未知的共振耦合,我们对所有通道的分支比进行了预测。

英文摘要:

Within the resonance chiral theory, we have studied the process of a tau lepton decaying into a vector resonance plus a pseudo-Goldstone meson and a tau neutrino. Two kinds of processes are discussed: (a) tau- --> (rho pi-,omega pi-, phi pi-, K*0 K-) nu(tau), belonging to Delta S=0 processes and (b) Delta S = 1 processes, such as tau- --> (rho K-, omega K-,phi K-,\bar{K*0} pi-) nu(tau). To fit the tau- --> omega pi- nu(tau) spectral function and the decay distribution of tau- --> omega K- nu(tau) to get unknown resonance couplings, we then make a prediction for branching ratios of all channels.
