本文报道了在$\sqrt{s} =$ 13 TeV质子-质子碰撞中与两个喷注相关联的W玻色子的电弱产生的测量结果。数据样本由CMS合作在LHC记录，对应于35.9 fb $^{-1}$的积分光度。在由不变质量$m_\mathrm{jj}$ $>$ 120 GeV和横动量$p_\mathrm{T j}$ $>$ 25 GeV定义的运动学区域中，对$\ellν$ jj终态（$\ellν$表示轻子-中微子对，j表示硬相互作用中产生的夸克）进行测量。在电子和μ子通道中测量该过程的横截面，得到每个通道的$σ_\mathrm{EW}$（Wj）= 6.23 $\pm$ 0.12（stat）$\pm$ 0.61（syst）pb，与领先阶标准模型预测一致。研究了信号富集区事件的额外强子活动，并将测量结果与预测进行了比较。最后的状态也被用来执行搜索异常三线性规范耦合。在有效场论的框架下，给出了与六维算子相关的反常三线性规范耦合的极限。相应的95%置信水平区间为$-$ 2.3 $<$ $c_{\mathrm{WWW}}/Λ^2$ $<$ 2.5 TeV $^{-2}$、$-$ 8.8 $<$ $c_{\mathrm{W}}/Λ^2$ $<$ 16 TeV $^{-2}$和$-$ 45 $<$ $c_{\mathrm{B}}/Λ^2$ $<$ 46 TeV $^{-2}$。将这些结果与CMS EW Zjj分析相结合，得到对$c_{\mathrm{WWW}}$耦合的约束：$-$ 1.8 $<$ $c_{\mathrm{WWW}}/Λ^2$ $<$ 2.0 TeV $^{-2}$。
英文摘要：
A measurement is presented of electroweak (EW) production of a W boson in association with two jets in proton-proton collisions at $\sqrt{s} =$ 13 TeV. The data sample was recorded by the CMS Collaboration at the LHC and corresponds to an integrated luminosity of 35.9 fb$^{-1}$. The measurement is performed for the $\ellν$jj final state (with $\ellν$ indicating a lepton-neutrino pair, and j representing the quarks produced in the hard interaction) in a kinematic region defined by invariant mass $m_\mathrm{jj}$ $>$ 120 GeV and transverse momenta $p_\mathrm{T j}$ $>$ 25 GeV. The cross section of the process is measured in the electron and muon channels yielding $σ_\mathrm{EW}$(Wjj) = 6.23 $\pm$ 0.12 (stat) $\pm$ 0.61 (syst) pb per channel, in agreement with leading-order standard model predictions. The additional hadronic activity of events in a signal-enriched region is studied, and the measurements are compared with predictions. The final state is also used to perform a search for anomalous trilinear gauge couplings. Limits on anomalous trilinear gauge couplings associated with dimension-six operators are given in the framework of an effective field theory. The corresponding 95% confidence level intervals are $-$2.3 $<$ $c_{\mathrm{WWW}}/Λ^2$ $<$ 2.5 TeV$^{-2}$, $-$8.8 $<$ $c_{\mathrm{W}}/Λ^2$ $<$ 16 TeV$^{-2}$, and $-$45 $<$ $c_{\mathrm{B}}/Λ^2$ $<$ 46 TeV$^{-2}$. These results are combined with the CMS EW Zjj analysis, yielding the constraint on the $c_{\mathrm{WWW}}$ coupling: $-$1.8 $<$ $c_{\mathrm{WWW}}/Λ^2$ $<$ 2.0 TeV$^{-2}$.
