论文摘要
具有$ W $或$ Z $玻色子腐烂的Higgs Boson的相关生产，以及Higgs Boson腐烂到$ b \ bar {B} $对，在高矢量 - 玻璃横向动量型中测量，超过250 GEV，超过250 GEV，ATLAS探测器。分析的数据对应于2015年至2018年之间的质子 - 普罗顿碰撞物中，以$ \ sqrt {s} = 13 $ tev收集，对应于139 fb $^{ - 1} $的集成亮度139 fb $^{ - 1} $。测得的信号强度定义为标准模型预测的测量信号产量的比率为$ 0.72 ^{+0.39} _ { - 0.36} $，对应于观察到的（预期）2.1（2.7）标准偏差。 Cross-sections of associated production of a Higgs boson decaying into $b$ quark pairs with a $W$ or $Z$ gauge boson, decaying into leptons, are measured in two exclusive vector boson transverse momentum regions, 250-400 GeV and above 400 GeV, and interpreted as constraints on anomalous couplings in the framework of a Standard Model effective field theory.
The associated production of a Higgs boson with a $W$ or $Z$ boson decaying into leptons and where the Higgs boson decays to a $b\bar{b}$ pair is measured in the high vector-boson transverse momentum regime, above 250 GeV, with the ATLAS detector. The analysed data, corresponding to an integrated luminosity of 139 fb$^{-1}$, were collected in proton-proton collisions at the Large Hadron Collider between 2015 and 2018 at a centre-of-mass energy of $\sqrt{s} = 13$ TeV. The measured signal strength, defined as the ratio of the measured signal yield to that predicted by the Standard Model, is $0.72 ^{+0.39}_{-0.36}$ corresponding to an observed (expected) significance of 2.1 (2.7) standard deviations. Cross-sections of associated production of a Higgs boson decaying into $b$ quark pairs with a $W$ or $Z$ gauge boson, decaying into leptons, are measured in two exclusive vector boson transverse momentum regions, 250-400 GeV and above 400 GeV, and interpreted as constraints on anomalous couplings in the framework of a Standard Model effective field theory.
