Descripción
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 ({\tilde{χ}}_1^{± }{\tilde{χ}}_2^0)
production in a simplified model of supersymmetry with the decays
{χ}_1^{±}\to {W}^{± }{\tilde{χ}}_1^0 and
{\tilde{χ}}_2^0\to H{χ}_1^0 . Values of
{m}_{{\tilde{χ}}_1^{± }} between 220 and 490 GeV are excluded
at 95% confidence level by this search when the {\tilde{χ}}_1^0 is
massless, and values of {m}_{{\tilde{χ}}_1^0} are 1 excluded up to
110 GeV for {m}_{{\tilde{χ}}_1^{± }}≈ 450 GeV. [Figure not
