与W-或H-相关的单顶夸克产生的双环软反常维度

Two-loop soft anomalous dimensions for single top quark associated production with a W- or H-

Nikolaos Kidonakis

摘要:

我目前的结果为双圈软异常尺寸的相关生产的一个顶夸克与W玻色子或带电希格斯玻色子。该计算使用了以不同形式呈现的大质量尖点反常维数的表达式,并且它允许软胶子在次-次-首对数(NNLL)精度下重新计算。从NNLL图解截面中,我导出了在LHC能量为7、10和14 TeV时bg -> tW-和bg -> tH-的近似NNLO截面。

英文摘要:

I present results for the two-loop soft anomalous dimensions for associated production of a single top quark with a W boson or a charged Higgs boson. The calculation uses expressions for the massive cusp anomalous dimension, which are presented in different forms, and it allows soft-gluon resummation at next-to-next-to-leading-logarithm (NNLL) accuracy. From the NNLL resummed cross section I derive approximate NNLO cross sections for bg -> tW- and bg -> tH- at LHC energies of 7, 10, and 14 TeV.
