我提出了近似的下一个下一个领导阶（aNNLO）的总截面和微分截面与顶夸克在大型强子对撞机的能量带电希格斯生产。过程$bg \rightarrow tH^-$的aNNLO结果是由软胶子修正的次次对数（NNLL）重算得到的。横截面的尺度和部分分布的不确定性。计算了顶夸克的横动量和快度分布。
I present approximate next-to-next-to-leading-order (aNNLO) total and differential cross sections for charged Higgs production in association with a top quark at LHC energies. The aNNLO results for the process $bg \rightarrow tH^-$ are derived from next-to-next-to-leading-logarithm (NNLL) resummation of soft-gluon corrections. Scale and parton-distribution uncertainties for the cross sections are shown. The top-quark transverse-momentum and rapidity distributions are also calculated.
