Search for electroweak production of charginos, neutralinos, and sleptons using leptonic final states in pp collisions at 8 TeV

Final states with exactly three leptons, four leptons, two same-sign leptons, two opposite-sign-same-flavor leptons plus two jets, and two opposite-sign leptons inconsistent with Z boson decay, are studied using a data sample consisting of an integrated luminosity of $19.5\,\text{fb}^{\text{$-$1}}$ of proton-proton collision data collected in 2012 with the CMS detector at $\sqrt{s}=8~{\text{TeV}}$. The observed event rates are in agreement with expectations from the standard model. The results are used to set limits on the direct production of charginos, neutralinos, and sleptons.
