低能QCD中的强子效应:包含τ轻子衰变

Hadronic effects in low-energy QCD: inclusive tau lepton decay

A. V. Nesterenko

摘要:

在QCD的色散近似下研究了τ轻子的强子衰变。强子化效应的重要性得到了令人信服的证明。手头的方法被证明是能够描述的实验数据τ轻子强子衰变的矢量和轴矢量通道。在两个通道中获得的QCD标度参数值的附近证明了所发展方法的自洽性。

英文摘要:

The inclusive tau lepton hadronic decay is studied within Dispersive approach to QCD. The significance of effects due to hadronization is convincingly demonstrated. The approach on hand proves to be capable of describing experimental data on tau lepton hadronic decay in vector and axial-vector channels. The vicinity of values of QCD scale parameter obtained in both channels bears witness to the self-consistency of developed approach.
