标题： Associated production of top quarks with the Higgs boson at $\sqrt{s}=13$ TeV

摘要： 顶夸克是标准模型中已知的最重的基本费米子，因此它与希格斯玻色子具有最大的耦合。 顶夸克与希格斯玻色子的关联产生，无论是成对（t$\bar{\rm{t}}$H）还是单个（tH），都提供了直接实验测量顶夸克-希格斯耦合$y_{\rm{t}}$的途径。 尽管t$\bar{\rm{t}}$H（tH）产生模式的发生率比胶子融合小约100（1000）倍，但它具有高度独特的实验特征，其中包括来自两个（单个）顶夸克衰变的轻子和/或喷流。 CMS收集的中心-of-质量能量为13 TeV且积分亮度高达$35.9\ \rm{fb}^{-1}$的ttH搜索的最新结果展示出来，并找到了令人信服的证据以足够精确地测量这一关键过程。 然而，为了确认或反驳之前观察到的超额现象，需要更高精度的数据集。 在中心-of-质量能量为13 TeV的初始tH产生模式搜索达到了与运行1分析相当的灵敏度。 显示英文摘要

摘要： The top quark, being the heaviest elementary fermion known in the Standard model, has the largest coupling to the Higgs boson. The associated production of top quarks with the Higgs boson, either in pairs (t$\bar{\rm{t}}$H) or singly (tH), provides direct experimental access to the top-Higgs coupling $y_{\rm{t}}$. The t$\bar{\rm{t}}$H (tH) production mode, while proceeding at a rate of about 100 (1000) times smaller than gluon fusion, bears a highly distinctive experimental signature, which includes leptons and/or jets from the decay of the two (single) top quarks. The latest results of ttH searches at a center-of-mass energy of 13 TeV corresponding to an integrated luminosity of up to $35.9\ \rm{fb}^{-1}$ as collected from CMS are shown and tantalizing evidence is found for measuring this crucial process with sufficient precision. However, higher precision data set is needed in order to confirm or disprove the previous observed excess. Initial searches for tH production mode at a center-of-mass energy of 13 TeV achieve comparable sensitivity to that of the Run 1 analysis.
