We propose a new method to discover light top squarks (stops) in theco-annihilation region at the Large Hadron Collider (LHC). The bino-likeneutralino is the lightest supersymmetric particle (LSP) and the lighter stopis the next-to-LSP. Such scenarios can be consistent with electroweakbaryogenesis and also with dark matter constraints. We consider the productionof two stops in association with two b-quarks, including pure QCD as well asmixed electroweak-QCD contributions. The stops decay into a charm quark and theLSP. For a higgsino-like light chargino the electroweak contributions canexceed the pure QCD prediction. We show the size of the electroweakcontributions as a function of the stop mass and present the LHC discoveryreach in the stop-neutralino mass plane.
