Combined exclusion limits assuming that the stop decays through ${\tilde{t}}_1^{}\to t{\tilde{\mathit{\chi }}}_1^0$ with different branching ratios $x$ and through ${\tilde{t}}_1^{}\to b{\tilde{\mathit{\chi }}}_1^{\pm }$ with branching ratios $1-x$. The limits assume $m_{{\tilde{\mathit{\chi }}}_1^{\pm }}=2m_{{\tilde{\mathit{\chi }}}_1^0}$, and values of $x$ from $0$ to $100\%$ are considered. For each branching ratio, the observed (with solid lines) and expected (with dashed lines) limits are shown
