论文摘要
希格斯玻色子的质量在$ h \ rightarrow zz^* \ rightarrow 4 \ ell $ decay频道中测量。该分析使用来自大型强子对撞机的质子 - 普罗顿碰撞数据，在2015年至2018年之间，Atlas检测器记录的13个TEV中心能量，对应于139 fb $^{ - 1} $的集成光度。希格斯玻色子质量的测量值为$ 124.99 \ pm0.18 \ text {（stat。）} \ pm0.04 \ text {（syst。）} $ GEV，基于相对于先前出版物的MUON的改进动量校准。该测量还采用了一个分析模型，该模型考虑了四lepton系统的不变质量分辨率，并考虑了深神网络网络的输出，从而从背景事件中区分信号。该测量与使用7和8 TEV $ PP $碰撞数据的相应测量相结合，从而导致Higgs Boson质量测量$ 124.94 \ PM0.17 \ text {（stat。）} \ pm0.03 \ pm0.03 \ text {（syst。）} $ GEV。
The mass of the Higgs boson is measured in the $H \rightarrow ZZ^* \rightarrow 4\ell$ decay channel. The analysis uses proton-proton collision data from the Large Hadron Collider at a centre-of-mass energy of 13 TeV recorded by the ATLAS detector between 2015 and 2018, corresponding to an integrated luminosity of 139 fb$^{-1}$. The measured value of the Higgs boson mass is $124.99\pm0.18\text{(stat.)}\pm0.04\text{(syst.)}$ GeV and is based on improved momentum-scale calibration for muons relative to previous publications. The measurement also employs an analytic model that takes into account the invariant-mass resolution of the four-lepton system on a per-event basis and the output of a deep neural network discriminating signal from background events. This measurement is combined with the corresponding measurement using 7 and 8 TeV $pp$ collision data, resulting in a Higgs boson mass measurement of $124.94\pm0.17\text{(stat.)}\pm0.03\text{(syst.)}$ GeV.
