We have analyzed the prospect of detecting a Higgs signal in mSUGRA/cMSSM based Supersymmetric (SUSY) model via chargino-neutralino () production at 8 TeV and 14 TeV LHC energies. The signal is studied in the [InlineEquation not available: see fulltext.] channel following the decays,

and
. In this analysis reconstruction of the Higgs mass out of two b jets plays a very crucial role in determining the signal to background ratio. We follow two techniques to reconstruct the Higgs mass: (A) adding momenta of two identified b jets, (B) jet substructure technique. In addition, imposing a certain set of selection cuts we observe that the significance is better for the method (B). We find that a signal can be observed for the Higgs mass ∼125 GeV with an integrated luminosity 100 fb−1 for both 8 TeV and 14 TeV LHC energies.
