K1共振态的强衰变

The strong decays of K1 resonances

Andrey Tayduganov, Emi Kou, Alain Le Yaouanc

摘要:

我们研究了K1--> K pi pi强相互作用衰变.利用3 P0夸克对产生模型导出基本参数化,详细讨论了如何从现有的实验数据中获得可能的准二体衰变通道的各种分波振幅以及它们的相对相位。我们得到的K1混合角为θ K1 = 60度,与以前的工作。我们的研究可用于提取辐射B-> K1 γ衰变的光子偏振测定所需的信息。

英文摘要:

We investigate the K1--> K pi pi strong interaction decays. Using the 3P0 quark-pair-creation model to derive the basic parametrization, we discuss in detail how to obtain the various partial wave amplitudes into the possible quasi-two-body decay channels as well as their relative phases from the currently available experimental data. We obtain the K1 mixing angle to be thetaK1= 60 deg, in agreement with previous works. Our study can be applied to extract the information needed for the photon polarization determination of the radiative B--> K1 gamma decay.
