Prospects for observing charginos and neutralinos at a 100 TeV proton-proton collider

We investigate the prospects for discovering charginos and neutralinos at a future pp collider with root s = 100 TeV. We focus on models where squarks and sleptons are decoupled - as motivated by the LHC data. Our initial study is based on models where Higgsinos form the main component of the LSP and W-inos compose the heavier chargino states (M-2 > mu), though it is straightforward to consider the reverse situation also. We show that in such scenarios W-inos decay into W-+/-, Z and h plus neutralinos almost universally. In the WZ channel we compare signal and background in various kinematical distributions. We design simple but effective signal regions for the trilepton channel and evaluate discovery reach and exclusion limits. Assuming 3000 fb(-1) of integrated luminosity, W-inos could be discovered (excluded) up to 1.1 (1.8) TeV if the spectrum is not compressed.
