改进TAUOLA和PHOKHARA中PDKEEPAAA电流的强子化
Improving the Hadronization of QCD currents in TAUOLA and PHOKHARA
摘要：
我们提出了我们的研究的强子化结构的矢量和轴向矢量电流导致衰变的τ成两个K介子和π介子。我们框架的基石是QCD的大N_C极限，在低能下表现出的手征结构和适当的渐近行为，由QCD统治，这是要求相关的形状因子。理论的耦合主要受这个过程的约束，通过分析BaBar关于e^+e^- -> KK π的数据，我们能够预言强子谱。
英文摘要：
We present our study of the hadronization structure of both vector and axial-vector currents leading to decays of the tau into two kaons and a pion. The cornerstones of our framework are the large-N_C limit of QCD, the chiral structure exhibited at low energies and the proper asymptotic behaviour, ruled by QCD, that is demanded to the associated form factors. The couplings of the theory are mostly constrained by this procedure and upon the analysis of BaBar data on e^+e^- -> KK pi we are able to predict the hadronic spectra.
