论文摘要
在强和弱相互作用下的非扰动量规不变性表明，质子包含希格斯粒子的非呈现价贡献。通过引入附加的Parton分布函数（PDF），我们研究了该预测的实验后果。 HERWIG 7事件发生器和参数化的CMS检测器模拟用于获得相当于LHC Run II数据集的方案的预测。我们使用这些来评估Higgs PDF对单个Lepton最终状态下PP-> TTBAR过程的影响。与名义模拟相比，我们得出了预期限制，它是价Higgs PDF形状的函数。我们还研究了Parton级别的过程PP-> ttz，以增加进一步的约束。
Non-perturbative gauge-invariance under the strong and the weak interactions dictates that the proton contains a non-vanishing valence contribution from the Higgs particle. By introducing an additional parton distribution function (PDF), we investigate the experimental consequences of this prediction. The Herwig 7 event generator and a parametrized CMS detector simulation are used to obtain predictions for a scenario amounting to the LHC Run II data set. We use those to assess the impact of the Higgs PDF on the pp->ttbar process in the single lepton final state. Comparing to nominal simulation we derive expected limits as a function of the shape of the valence Higgs PDF. We also investigate the process pp->ttZ at the parton level to add further constraints.
