Model-dependent exclusion contour at 95 CL on the chargino and a next-to-lightest neutralino mass versus the mass difference between chargino and LSP in the C1N2-Wh model. The observed limit is given by the solid line with the signal cross-section uncertainties shown by the dotted lines as indicated in the text. Expected limits are given by the dashed line with uncertainties shown by the shaded band. The observed and expected limit contours from the previous ATLAS analysis of the same data sample using standard cut-and-count methods are also shown for comparison.
