Search for electroweak production of charginos and neutralinos in multilepton final states in pp collision data at $\sqrt{s}=13~\mathrm{TeV}$

Searches are presented for direct electroweak production of charginos and neutralinos in signatures with two light leptons of the same charge and with three or more leptons including up to two hadronically decaying $\tau$ leptons. The results are based on a sample of proton-proton collision data collected at a center-of-mass energy $\sqrt{s}=13~\mathrm{TeV}$ recorded with the CMS detector, corresponding to an integrated luminosity of $35.9~\mathrm{fb}^{-1}$. The observed event rates are in agreement with expectations from the standard model. These results probe charginos and neutralinos with masses up to values between 225 and 1150 GeV, depending on the model parameters assumed. These results significantly extend the phase space probed with previous searches.
