在质心能量为13TeV的质子-质子碰撞中，在大型强子对撞机上测量了Z玻色子衰变为两个中微子的总和微分基准面。这些数据是由CMS探测器在2016年收集的，对应的积分光度为35.9fb−1。在这些测量中，选择的事件包含横向动量不平衡和一个或多个高能喷流。测量了作为Z玻色子横向动量函数的基准微分截面。这一结果与之前对Z玻色子带电轻子衰变的测量结果相结合。测量了Z玻色子横动量大于200GeV的事件的总基准面。
Measurements of the total and differential fiducial cross sections for the Z boson decaying into two neutrinos are presented at the LHC in proton-proton collisions at a center-of-mass energy of 13 TeV. The data were collected by the CMS detector in 2016 and correspond to an integrated luminosity of 35.9 fb− 1. In these measurements, events are selected containing an imbalance in transverse momentum and one or more energetic jets. The fiducial differential cross section is measured as a function of the Z boson transverse momentum. The results are combined with a previous measurement of charged-lepton decays of the Z boson. The measured total fiducial cross section for events with Z boson transverse momentum greater than 200 GeV isfb.
