Table 1.

Sparticle masses of the benchmark points GMSB, P1 and P2 (in GeV), event yields including 30 % systematic errors from the simulation of the benchmark points GMSB, P1 and P2 in the six signal regions of the CMS on-Z searches in [3], and in the most constraining signal regions CT, EM and ET of the ATLAS search [17]. The ranges of $E_{\text{T}}^{\mathrm{miss}}$ for the six CMS signal regions are given in GeV. The last line indicates the contributions to the ATLAS on-Z signal region
