| Abstract: A direct search for electroweak production of charginos and neutralinos is presented. Events with three or more leptons, with up to two hadronically decaying $\tau$ leptons, or two leptons of the same charge are analyzed. The data sample consists of 137 fb$^{-1}$ of proton-proton collisions recorded with the CMS detector at the LHC. The results are interpreted in terms of several simplified models approximating a broad range of production and decay scenarios for charginos and neutralinos. A parametric neural network is used to target several of the models suffering from large backgrounds, while a search using orthogonal search regions is provided for all the models, simplifying alternative theoretical interpretations of the results. Depending on the model hypotheses, chargino and neutralino masses between 1450 GeV and 300 GeV are excluded at 95% confidence level. | ||
