Abstract
Searches for “natural” supersymmetry (SUSY) scenarios are presented in which only neutralinos, charginos, and potentially also the top-quark superpartner (stop) are assumed to be accessible, and which result in multi-boson final states. These efforts rely on a novel and versatile method where by the narrow H to gamma gamma resonance is used to identify events with a Higgs boson candidate, and to determine backgrounds. This provides a sufficiently clean search environment to largely overcome the small H to gamma gamma branching fraction. First, a search is performed for stop pair production resulting in 2b2H. Events with two photons forming a Higgs boson candidate and at least two b-jets are selected and missing transverse energy is examined. Then, the diphoton components of a comprehensive search for electroweak production of neutralinos and charginos are presented, which may decay to Higgs and Z, bosons and undetected lightest SUSY particles (LSPs). This latter search is then reinterpreted in terms of chargino-neutralino pair production, leading to HW± states with Emiss. The searches are performed using 19.5 1/fb of proton-proton collisions at sqrt(s) = 8 TeV, recorded in the Compact Muon Solenoid (CMS) detector. No compelling evidence for new physics is found and 95% confidence limits are set.
