Higgs production in association with a Z boson#
We present here plots and animations related to Section 4.4 and 5.3 of [Gomez Ambrosio et al., 2022].
We consider Higgs production in association with a Z boson in the \(Z h \rightarrow \ell^{+} \ell^{-} \bar{b} b\) final state, at the LHC 14 TeV.
Models#
Trained models for \(p p \rightarrow Z h \rightarrow \ell^{+} \ell^{-} \bar{b} b\) are presented in Table 1. The models are trained on either a single feature, \(p_{T}^{Z}\) (calculated as the \(p_{T}\) of the final-state leptons), or the full set of 7 kinematic features. More details about the kinematic features used in the neural network training can be found in the next section.
