标题： Quadratic Mass Corrections of Order $α_s^3 m_q^2/s$ to the Decay Rate of Z- and W- Bosons

摘要： 我们解析计算了两个轴矢流相关函数的吸收部分的二次质量修正，阶数为$\alpha_s^3 m_q^2/s$。 这使我们能够找到$\Gamma(W -->hadrons)$的阶数为$\alpha_s^3 m_q^2/M^2_W$的修正，以及对$\Gamma(Z -->hadrons)$的类似修正。 显示英文摘要

摘要： We analytically compute quadratic mass corrections of order $\alpha_s^3 m_q^2/s$ to the absorptive part of the (non-diagonal) correlator of two axial vector currents. This allows us to find the correction of order $\alpha_s^3 m_q^2/M^2_W$ to the $\Gamma(W -->hadrons)$ as well as similar corrections to $\Gamma(Z -->hadrons)$.
