Electroweak SUSY Searches at CMS using LHC-data collected at $\sqrt{s} = 8$ TeV

The searches presented in this summary correspond to the electroweak (EWK) pair production of neutralinos ($\tilde{\chi}^{0}_{i}$) and charginos ($\tilde{\chi}^{\pm}_{1}$) decaying to Higgs (h), Z, and W bosons, and the lightest supersymmetric particle (LSP). The searches were performed using 19.5 $fb^{-1}$ of data from proton-proton collisions at the LHC, at a center of mass energy of 8 TeV collected in 2012 by the CMS detector. The main production modes correspond to pair production of $\tilde{\chi}^{0}_{i}$, where each $\tilde{\chi}^{0}_{i}$ decays to a h or a Z boson and a LSP, resulting in final states with hh, hZ and ZZ, with associated missing transverse energy ($E^{miss}_{T}$). A second mechanism is the pair production $\tilde{\chi}^{\pm}_{1}\tilde{\chi}^{0}_{i}$, which leads to hW states in addition to $E^{miss}_{T}$. The observed data is consistent with the estimation of the SM backgrounds. Therefore, no evidence of supersymmetric particles is found, and 95\% confidence level upper limits are set on the pair production cross section of the respective process as a function of the $\tilde{\chi}^{0}_{i}$ and $\tilde{\chi}^{\pm}_{1}$ masses.
