论文摘要
使用Brodsky-Lepage-Mackenzie（BLM）最佳尺度设置计算了Sudakov运动区域中横向摩托依赖性（TMD）操作员仅速度速度演变（TMD）算子的耦合常数的比例。耦合常数的有效论点是在TMD分布的横向动量和能量之间的对数尺度中的一半。对于夸克和Gluon TMD，求解了所得的速度仅速度进化方程。
The scale of a coupling constant for rapidity-only evolution of transverse-momentum dependent (TMD) operators in the Sudakov kinematic region is calculated using the Brodsky-Lepage-Mackenzie (BLM) optimal scale setting. The effective argument of a coupling constant is halfway in the logarithmical scale between the transverse momentum and energy of TMD distribution. The resulting rapidity-only evolution equation is solved for quark and gluon TMDs.
