analysis on the two window mass selections has been used to obtain the final numbers of data and expected background events from SM processes.. 2e + 6 jets channel: ¯ U ¯ D ¯ D
Figure 3: Slepton search with the λ122 coupling: the distributions of the energy of the most energetic lepton (top left) and the lepton isolation angle (top right) are shown at
The same preselection criteria as described in Section 3.1.2 were used, but since in the case of stop pair production the final state always contains two jets, a minimum multiplicity
Figure 6: Number of expected events (continuous line) data events (black dots) versus signal efficiency for a chargino mass of 80 GeV and a neutralino mass of 50 GeV in the
The results of the searches for 4τ and 2e2τ final states, from sneutrino pair direct decays, were combined to obtain lower limits on the sneutrino mass. The signal output

Figure 3: (a) distributions of the discriminant variable at √ s = 205 − 207 GeV for data (dots), SM background simulation (shadowed region) and signal (thick line) with
An upper limit at 95% CL on the total number of signal events ( N up ) compatible with the data and expected background was then calculated for each ( M ˜ ν , Γ ν ˜ ) bin,
