论文摘要
我们研究了LHC与C-JET的W玻色子的生产。我们首次计算NNLO QCD校正的完整集，以对此过程的主要CKM-DIAGONAL贡献。这两个签名，$ {\ rm p} {\ rm p} \toμ^+ν_μ{\ rm j} _ {\ rm c} $和$ {\ rm p} {\ rm p} {\ rm p} {\ rm p} \ toμ^ - \barν_μ{我们介绍了两个签名中的每个签名及其比率的基准横截面和差分分布的预测。将理论预测与ATLAS的测量值（$ 7 \）进行了比较； {\ rm tev} $。这项工作的结果对于强子小面包的相关浓度产生的精确描述以及从NNLO QCD中LHC数据的奇怪Quark含量确定奇怪的QUARK含量至关重要。
We study the production of a W boson in association with a c-jet at the LHC. We calculate, for the first time, the complete set of NNLO QCD corrections to the dominant CKM-diagonal contribution to this process. Both signatures, ${\rm p}{\rm p}\to μ^+ν_μ{\rm j}_{\rm c}$ and ${\rm p}{\rm p}\to μ^-\barν_μ{\rm j}_{\rm c}$ are considered. We present predictions for fiducial cross sections and differential distributions for each one of the two signatures as well as for their ratio. The theoretical predictions are compared with ATLAS measurements at $7 \; {\rm TeV}$. The results of this work are essential for the precision description of associated heavy flavor production at hadron colliders and for the determination of the strange-quark content of the proton from LHC data in NNLO QCD.
