我讨论了强子碰撞中的顶级夸克产生。给出了软胶子恢复公式及其从因式分解和重整化群演化中的推导，以及在eikonal近似下软反常维度的两圈计算。讨论了次次前导软胶子修正对顶-反顶对产生、单顶产生以及与W玻色子或带电希格斯玻色子有关的总截面、顶夸克横动量和快度分布的贡献。
I discuss top quark production in hadronic collisions. I present the soft-gluon resummation formalism and its derivation from factorization and renormalization-group evolution, and two-loop calculations of soft anomalous dimensions in the eikonal approximation. I discuss the contributions of next-to-next-to-leading order (NNLO) soft-gluon corrections to the total cross sections and top-quark transverse momentum and rapidity distributions for top-antitop pair production, and for single-top production in the t and s channels and in association with a W boson or a charged Higgs boson.
