在单顶生产过程中，我提出了近似的次-次-次-序（aNNLO）横向动量（$p_T$）分布。aNNLO结果来源于微分截面上软胶子修正的次次前对数（NNLL）恢复。LHC能量的单顶和单反顶$p_T$分布显示在$t$通道、$s$通道和$tW$产生中。
I present approximate next-to-next-to-leading-order (aNNLO) transverse-momentum ($p_T$) distributions in single-top production processes. The aNNLO results are derived from next-to-next-to-leading-logarithm (NNLL) resummation of soft-gluon corrections in the differential cross section. Single-top as well as single-antitop $p_T$ distributions are shown in $t$-channel, $s$-channel, and $tW$ production for LHC energies.
