Electroweak SUSY Searches at CMS using LHC-data collected at
چکیده انگلیسی

The searches presented in this summary correspond to the electroweak (EWK) pair production of neutralinos () and charginos () 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 , where each 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 (). A second mechanism is the pair production , which leads to hW states in addition to . 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 and masses.
