Query: Neutralino dark matter confronted by the LHC constraints on Electroweak
  SUSY signals   The supersymmetric particles (sparticles) belonging exclusively to the
electroweak sector of the minimal supersymmetric standard model (MSSM) may hold
the key to the observed dark matter relic density in the universe even if all
strongly interacting sparticles are very heavy. The importance of the light EW
sparticles in DM physics and in producing spectacular collider signals is
emphasized. It is shown that even the preliminary data on the direct searches
of these sparticles at the LHC, significantly constrain the parameter space of
the MSSM compatible with the observed relic density and provide useful hints
about the future search prospects. If in addition to the electroweak sparticles
the gluinos are also within the reach of the LHC experiments, then the gluino
mass limits in the light slepton scenario obtained via the canonical jets +
$\met$ channel may be relaxed by as much as 25 $%$ compared to the existing
limits. But the corresponding same sign dilepton (SSD) + jets + $\met$ signal
will yield enhanced limits competitive with the strongest limits currently
available. This is illustrated with the help of benchmark scenarios at the
generator level using PYTHIA. If the gluinos are just beyond the current reach
of the LHC, then the generic n-lepton + m-jets + missing energy signal may
discriminate between different DM producing mechanisms by comparing the signals
corresponding to different values of n. This is illustrated by simulating the
signals for n = 0 and n = 2 (the SSD signal).
