Search for electroweak production of charginos and neutralinos in the WH final state at 13 TeV

A search is performed for beyond the standard model physics in events with a leptonically-decaying W boson, a Higgs boson decaying to a pair of b-quarks, and missing transverse energy, using 12.9~fb$^{-1}$ of data recorded by CMS in 2016 at $\sqrt{s} = 13$~TeV. This signature is predicted to occur, for example, in supersymmetric models from electroweak production of gauginos. The observed data are in agreement with the standard model prediction. The results are used to set cross section limits on chargino-neutralino production in a simplified model of supersymmetry with the decays $\tilde{\chi}_{1}^{\pm} \rightarrow W \tilde{\chi}_{1}^{0}$ and $\tilde{\chi}_{2}^{0} \rightarrow H \tilde{\chi}_{1}^{0}$.
