在考虑和的情况下,我们用改进的Bethe-Salpeter(B-S)方法研究了介子排斥弱衰变中和的产生。利用相对论性B-S方程和Mandeltmann公式计算了相应的衰变形状因子。相应分支比的预测为:和。这将为我们提供一种新的方法来观察介子衰变,并在未来,以及提高对介子衰变的认识。
Consideringandasand, we study the productions ofandin exclusive weak decays ofmeson by the improved Bethe-Salpeter(B-S) Method. Using the relativistic B-S equation and Mandelstam formalism, we calculate the corresponding decay form factors. The predictions of the corresponding branching ratios are:and. That will provide us a new way to observe theandin the future, as well as to improve the knowledge ofmeson decay.
