Descripción
This poster presents searches for supersymmetry in compressed scenarios using 20.3 fb-1 of proton-proton collision data at sqrt(s) = 8 TeV recorded by the ATLAS experiment at the LHC. The analysis has been optimized for the stop decaying into a charm quark plus a neutralino SUSY signal. Different signal regions have been defined with different thresholds in ETmiss and Pt of the leading jet, with at most three jets. Limits are set on the visible cross-section. Interpretations for the stop pair production (stop decaying to charm plus neutralino and four body decay) and sbottom pair production (sbottom decaying to bottom plus neutralino) are studied. Results are presented in terms of exclusion limits in the stop-neutralino and sbottom-neutralino mass planes.
