论文摘要
在质子 - 普罗顿（Proton-Proton）碰撞中，在LHC中，在13 TeV的质量中心能量中，在LHC中呈现了Z玻色子腐烂成两个中微子的总基准横截面的测量值。数据是由CMS检测器在2016年收集的，对应于35.9 fb $^{ - 1} $的集成光度。在这些测量值中，选择了包含横向动量和一种或多种能量喷射的不平衡的事件。基准差分横截面是作为Z玻色子横向动量的函数测量的。结果与先前对Z玻色子的带电勒普顿衰变的测量结合。 Z玻色子横向动量大于200 GEV的事件的测量总基准横截面为3000 $^{+180} _ { - 170} $ fb。
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 is 3000 $^{+180}_{-170}$ fb.
