noimg: \small Average centre-of-mass energy and corresponding luminosities of the analysed data sample.: \small Final state topologies studied in the different GMSB scenarios.

\small Excluded neutralino mass at 95$\%$ confidence level as a function of its lifetime in the neutralino NLSP scenario. The excluded areas are obtained by the scan described in Section~\ref{scan} for negative $\mu$, $N_5 = 1$, $M_{\mathrm{mess}} = 10^{12}\gevcc$, $\tanb = 20$ and any $\Lambda$. The short and medium lifetime cases, when at least one $\neu$ decays inside the detector, are covered by the acoplanar photons and non-pointing photon searches. For long-lived neutralinos the gravity mediated searches for charginos and sleptons are used.

\small Excluded $\stau_{\mathrm{R}}$ mass at 95$\%$ C.L. as a function of its lifetime (shaded area) from direct searches. Dashed curves give the limits from the different topologies. The search for acoplanar leptons covers the case of small lifetimes, searches for tracks with large impact parameter and for kinks are used in the intermediate range, whereas for very large lifetimes a search for heavy stable charged particles is performed. The dotted curve gives the expected limit.

\small a) Selection efficiencies for the six different event topologies versus $\Delta m$ = $m_{\neu}$-$m_{\slep}$ in the zero slepton lifetime case. The spread of points observed for a given topology is due to different values of neutralino and slepton masses. b) Probability for a signal stau-pair event to be selected by at least one of the six topological searches versus slepton decay length. The set of curves with higher efficiency in the 0.1\,cm area corresponds to the prompt decay selection. Those peaking at $\sim$10\,cm correspond to the short and long decay length selection. Different lines correspond to different points in the ($m_{\neu}$,$m_{\stau}$) space.

\small Regions excluded by the different analyses described in the text at 95$\%$ confidence level in the ($m_{\neu},m_{\stau}$) plane, for a) short NLSP lifetimes ($m_{\grav} \leq 10\evcc$) and b) long NLSP lifetimes ($m_{\grav} \geq 1\kevcc$). Points in the dark region are not accessible to the scan. The absolute NLSP mass limit is set at 54$\gevcc$ in b) by the intersection of chargino and slepton searches.
