我们提出了一个蒙特卡罗事件发生器YFSWW3版本1.16，用于电子-正电子碰撞中w对的产生和衰变过程。它包括WW产生阶段的O （α）电弱辐射校正以及在ynie - frautschi - suura （YFS）排他幂框架内实现的超前对数（LL）近似中的O （α3）初始态辐射（ISR）校正。W衰变中的光子辐射由专用程序PHOTOS生成，最高可达O (α2) LL，归一化为W分支比。该程序与τ衰变库TAUOLA和夸克碎片/强子化包JETSET接口。包括用于计算Born水平和ISR近似下的微分截面和总截面的半解析代码KorWan。
We present the Monte Carlo event generator YFSWW3 version 1.16 for the process of W-pair production and decay in electron–positron collisions. It includes O (α) electroweak radiative corrections in the WW production stage together with the O (α3) initial-state-radiation (ISR) corrections in the leading-logarithmic (LL) approximation, implemented within the Yennie–Frautschi–Suura (YFS) exclusive exponentiation framework. The photon radiation in the W decays is generated by the dedicated program PHOTOS up to O (α2) LL, normalized to the W branching ratios. The program is interfaced with the τ decay library TAUOLA and the quark fragmentation/hadronization package JETSET. The semi-analytical code KorWan for the calculations of the differential and total cross-sections at the Born level and in the ISR approximation is included.
