我们给出了与弱电玻色子相关的单顶夸克产生的高阶软胶子辐射修正的结果,包括通过反常的FCnC耦合产生的$t\γ和$tZ。我们给出了LHC能量下的总截面和微分分布的结果。我们使用$K$-因子来表示修正相对于前导顺序的重要性,并讨论了结果的不确定性和重要性。
We present results for higher-order soft-gluon radiative corrections for single top-quark production in association with electroweak bosons, including $t\gamma$ and $tZ$ production via anomalous FCNC couplings. We provide results for the total cross sections and differential distributions at LHC energies. We use $K$-factors to show the significance of the corrections compared to leading order, and we discuss uncertainties and the importance of the results.
