单顶和顶对顶截面

Single-top and top-antitop cross sections

Nikolaos Kidonakis

摘要:

我提出了高阶计算,包括软胶子修正,单顶和顶-反顶生产截面和微分分布。对于单顶生产,结果在标准模型中的三个不同的通道,为相关的生产与带电的希格斯粒子,并为涉及异常耦合的过程。对于顶-反顶对的产生,给出了各种LHC能量下的总截面和顶夸克横动量及快度分布。

英文摘要:

I present high-order calculations, including soft-gluon corrections, for single-top and top-antitop production cross sections and differential distributions. For single-top production, results are presented for the three different channels in the Standard Model, for associated production with a charged Higgs, and for processes involving anomalous couplings. For top-antitop pair production, total cross sections and top-quark transverse-momentum and rapidity distributions are presented for various LHC energies.
