The data collected using the CMS detector at the LHC correspond to an integrated luminosity of 35.9 fb(-1). The observed event yields are consistent with the expectations from the standard model. The results are interpreted in terms of pair production of charginos and neutralinos ((chi) over tilde (+/-)(1) and (chi) over tilde (0)(2)) with nearly degenerate masses, as expected in natural supersymmetry models with light higgsinos, as well as in terms of the pair production of top squarks ((t) over tilde), when the lightest neutralino and the top squark have similar masses. At 95% confidence level, wino-like (chi) over tilde (+/-)(1)/(chi) over tilde (0)(2) masses are excluded up to 230GeVfor a mass difference of 20GeV relative to the lightest neutralino. In the higgsino-like model, masses are excluded up to 168GeV for the same mass difference. For (t) over tilde pair production, top squark masses up to 450GeVare excluded for a mass difference of 40GeV relative to the lightest neutralinoCONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQCOORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESFUNDAÇÃO CARLOS CHAGAS FILHO DE AMPARO À PESQUISA DO ESTADO DO RIO DE JANEIRO - FAPERJFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPAbertoUNIVERSIDADE ESTADUAL DE CAMPINASChinellato, José Augusto, 1950-Manganote, Edmilson José Tonelli, 1962-2018info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://hdl.handle.net/20.500.12733/1664321CHINELLATO, José Augusto; MANGANOTE, Edmilson José Tonelli.
