Search for electroweak production of charginos and neutralinos in WH events in proton-proton collisions at √s=13 TeV
Results are reported from a search for physics beyond the standard model in proton-proton collision events with a charged lepton (electron or muon), two jets identified as originating from a bottom quark decay, and significant imbalance in the transverse momentum.

| Summary: | Results are reported from a search for physics beyond the standard model in
proton-proton collision events with a charged lepton (electron or muon), two jets identified
as originating from a bottom quark decay, and significant imbalance in the transverse
momentum. The search was performed using a data sample corresponding to 35.9 fb−1
,
collected by the CMS experiment in 2016 at √
s = 13 TeV. Events with this signature can
arise, for example, from the electroweak production of gauginos, which are predicted in
models based on supersymmetry. The event yields observed in data are consistent with
the estimated standard model backgrounds. Limits are obtained on the cross sections for
chargino-neutralino (χe
