ρ~0→π~+π~-衰变的么正计算和ρ~0极化插入的虚部
A Unitary Calculation of ρ￣0→π￣+π￣- Decay and the Imaginary Part of ρ￣0 Polarization Insertion
【摘要】 本文给出了ρ~０→π~＋π~－衰变的么正计算及其衰变率和ρ~２极化插入的关系．ρ~０极化插入的虚部是用维度积分的方法来计算．极化插入虚部的计算方法是普适的．
【Abstract】 A unitary calculation of the ρ￣0→π￣+π￣- decay and its relation with the ρ￣0 polarization insertion are shown. The imaginary part of the ρ￣0 polarization insertion is calculated by using dimensional integration method. The approaches used in this paper to draw the imaginary part of a polarization insertion are convenient and universal,and can be extensively used for other processes.
