abstract = {A direct search for electroweak production of charginos and neutralinos is presented. Events with three or four leptons, with up to two hadronically decaying τ leptons, or two same-sign light leptons are analyzed. The data sample consists of 137 fb−1 of proton-proton collisions with a center of mass energy of 13 TeV, recorded with the CMS detector at the LHC. The results are interpreted in terms of several simplified models. These represent a broad range of production and decay scenarios for charginos and neutralinos. A parametric neural network is used to target several of the models with large backgrounds. In addition, results using orthogonal search regions are provided for all the models, simplifying alternative theoretical interpretations of the results. Depending on the model hypotheses, charginos and neutralinos with masses up to values between 300 and 1450 GeV are excluded at 95% confidence level.},
organization = {We congratulate our colleagues in the CERN accelerator departments for the excellent
performance of the LHC and thank the technical and administrative staffs at CERN and
at other CMS institutes for their contributions to the success of the CMS effort. In addition,
we gratefully acknowledge the computing centers and personnel of the Worldwide
LHC Computing Grid and other centers for delivering so effectively the computing infrastructure
essential to our analyses. Finally, we acknowledge the enduring support for the
construction and operation of the LHC, the CMS detector, and the supporting computing
infrastructure provided by the following funding agencies: BMBWF and FWF (Austria);
