Abstract
(type = abstract)
We present the individual and combined results of several analyses that search for the next-to-lightest supersymmetric particle (NLSP) in the context of the Natural Higgsino NLSP model. The model posits that the NLSP is in a pure Higgsino energy eigenstate, and upon production mediated by electroweak processes, decays to either a Higgs or Z boson and the lightest supersymmetric particle (LSP), which is in a pure Bino energy eigenstate. The Higgs and Z bosons then decay in the Standard Model (SM) fashion, leading to a number of possible final states, all of which include missing transverse energy (MET) coming from the LSP. Six independent analyses search for the existence of the Higgsino-like NLSP by examining events that have the signature of a particular final state of the model. In addition to MET, these unique final states include multileptons, four b-jets, two photons and two b-jets, two photons and a lepton, two b-jets and two leptons, and two light-flavored jets and two leptons. The data used was collected during the 2012 run of the CMS experiment at $sqrt{s}$ = 8 TeV and $L_{int} = 19.5fb^{-1}$. No physics beyond the Standard Model was discovered. We therefore set limits on the mass of the Higgsino and the branching fraction of the Higgsino decays to Higgs and Z bosons.
