We investigate multi-lepton signals produced by ElectroWeakino (EWino) decays
in the MSSM and the TMSSM scenarios with sfermions, gluinos and non Standard
Model Higgses at the TeV scale, being the Bino electroweak-scale dark matter.
We recast the present LHC constraints on EWinos for these models and we find
that wide MSSM and TMSSM parameter regions prove to be allowed. We forecast the
number of events expected in the signal regions of the experimental
multi-lepton analyses in the next LHC runs. The correlations among these
numbers will help to determine whether future deviations in multi-lepton data
are ascribable to the EWinos, as well as the supersymmetric model they
originate from.Comment: 33 pages, 10 figures, 3 table
