Exclusion limits assuming that the stop decays through ${\tilde{t}}_1^{}\to b+{\tilde{\mathit{\chi }}}_1^{\pm }\to b+W^{(\ast )}+{\tilde{\mathit{\chi }}}_1^0$ with branching ratio of 100 % assuming a fixed stop mass of $m_{{\tilde{t}}_1^{}}=300$ GeV. The region below the purple line and above the blue line, indicated by a light shading, is excluded
