An integrated luminosity of 36.1 $\mathrm{fb}^{-1}$ is assumed when calculating the weighted yields. For the derivation skim at least one of the following four criteria is required: $H_{\mathrm{T}}$ $&gt;$ 150 GeV; at least one loose electron with $p_{\mathrm{T}}$ $&gt;$ 100 GeV or at least two loose electrons with $p_{\mathrm{T}}$ $&gt;$ 20 GeV; at least one muon with $p_{\mathrm{T}}$ $&gt;$ 100 GeV or at least two muons with $p_{\mathrm{T}}$ $&gt;$ 20 GeV; or at least one photon with $p_{\mathrm{T}}$ $&gt;$ 100 GeV or at least two photons with $p_{\mathrm{T}}$ $&gt;$ 50 GeV.

Exclusion limits are placed in terms of the top-squark and neutralino masses. Assuming a branching ratio of 100% to $t \tilde\chi^0_1$, top-squark masses in the range 450--950 GeV are excluded for $\tilde\chi^0_1$ masses below 160 GeV. In the case where $m_{\tilde{t}_1}\sim m_t+m_{\tilde\chi^0_1}$, top-squark masses in the range 235--590 GeV are excluded.
