A search for Supersymmetry signals with Same-Sign Dileptons in the
final state at the Large Hadron Collider is presented. The results are
based on 976 pb-1 of pp collision data recorded by the Compact Muon
Solenoid experiment at 7 TeV centre of mass energy. The analysis
strategy for channels including a hadronically decaying τ (eτ, µτ, ττ ) is
discussed in detail. The numbers of observed events are compatible with
the expectation from Standard Model processes in all the considered
channels with a total of 2.9 ± 1.7 predicted and 3 observed. An Upper
Limit of total observed events from New Physics is extracted at the
95% Confidence Level and is equal to 5.8. The results are interpreted
in the Constrained Minimal Supersymmetric Standard Model and a
simplified Supersymmetry model favouring τ channels characterised by [Mathematical formula appears here. To view, please open pdf attachment].
A lower limit of 400 GeV on the gluino mass is set in the simplified
model for neutralino masses up to 350 GeV, with the exception of the
region around mğ ≈ mLSP. This exclusion extends to gluino masses of
up to 620 GeV for neutralino masses of less than 100 GeV.
