论文摘要
希格斯玻色子的包含和差异基准横截面以$ h \ to zz^{*} \ to 4 \ ell $（$ \ ell = e，μ$）衰减通道测量。结果基于质子$ - $质子的质子碰撞数据，该数据在大型强子对撞机上以13 TEV的中心能量产生，并于2015年至2018年由地图集检测器记录，相当于139 fb $^{ - 1} $的集成亮度。 $ h \至zz^{*} \ to 4 \ ell $过程的包含信托横截面为$σ_\ mathrm {fid} = 3.28 \ pm 0.32 $ 0.32 $ fb，与标准模型预测$σ_\ Mathrm {fid，sm} = 3.41 = 3.41 $ 0.18 $ fb。测量了各种对Higgs玻色子的生产和衰减敏感的可观察到的基准横截面。所有测量都与标准模型预测一致。结果用于限制异常的希格斯玻色子与标准模型颗粒的相互作用。
Inclusive and differential fiducial cross sections of the Higgs boson are measured in the $H \to ZZ^{*} \to 4\ell$ ($\ell = e,μ$) decay channel. The results are based on proton$-$proton collision data produced at the Large Hadron Collider at a centre-of-mass energy of 13 TeV and recorded by the ATLAS detector from 2015 to 2018, equivalent to an integrated luminosity of 139 fb$^{-1}$. The inclusive fiducial cross section for the $H \to ZZ^{*} \to 4\ell$ process is measured to be $σ_\mathrm{fid} = 3.28 \pm 0.32$ fb, in agreement with the Standard Model prediction of $σ_\mathrm{fid, SM} = 3.41 \pm 0.18 $ fb. Differential fiducial cross sections are measured for a variety of observables which are sensitive to the production and decay of the Higgs boson. All measurements are in agreement with the Standard Model predictions. The results are used to constrain anomalous Higgs boson interactions with Standard Model particles.
