Search for electroweak production of charginos and neutralinos in multilepton final states in proton-proton collisions at √s=13 TeV
Results are presented from a search for the direct electroweak production of charginos and neutralinos in signatures with either two or more leptons (electrons or muons) of the same electric charge, or with three or more leptons, which can include up to two hadronically decaying tau leptons. The...

| description | Results are presented from a search for the direct electroweak production
of charginos and neutralinos in signatures with either two or more leptons (electrons or
muons) of the same electric charge, or with three or more leptons, which can include up
to two hadronically decaying tau leptons. The results are based on a sample of protonproton
collision data collected at √
s = 13 TeV, recorded with the CMS detector at the
LHC, corresponding to an integrated luminosity of 35.9 fb−1
. The observed event yields are
consistent with the expectations based on the standard model. The results are interpreted
in simplified models of supersymmetry describing various scenarios for the production and
decay of charginos and neutralinos. Depending on the model parameters chosen, mass
values between 180 GeV and 1150 GeV are excluded at 95% CL. These results significantly
extend the parameter space probed for these particles in searches at the LHC. In addition,
results are presented in a form suitable for alternative theoretical interpretations. |
