We have analyzed the prospect of detecting a higgs signal in mSUGRA/CMSSM based Supersymmetric(SUSY) model via chargino-neutralino($\CH_1\N0_2$) production at 8 TeV and 14 TeV LHC energy. The signal is studied in the channel with $\ell + b \bar b + \PMET$ following the decays, $\CH_1 \to W^\pm \N0_1$, $\N0_2 \to \N0_1 h$ and $h \to b \bar b$. 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 higgs mass: (A) using two identified b-jets, (B) using jet substructure technique. In addition, imposing a certain set of selection cuts we observe the significance is better for the latter method. We find that a viable signal can be obtained for the higgs mass $\sim$ 125 GeV with an integrated luminosity 100 $\lumi$ for both 8 and 14 TeV LHC energy.

We follow two techniques to reconstruct higgs mass: (A) using two identified b-jets, (B) using jet substructure technique.

We find that a viable signal can be obtained for the higgs mass $\sim$ 125 GeV with an integrated luminosity 100 $\lumi$ for both 8 and 14 TeV LHC energy.

Conversely, the discovery sensitivity for BSM physics through Higgs production has been studied in the context of the MSSM with a bino LSP [ref] , a gravitino LSP [ref] , and additional feebly coupled LSPs [ref] , as well as in the context of vector-like heavy quarks [ref] .

However, if we use NLO cross sections by multiplying K-factors which is $∼$ 1.5 for signal [ref] and about 1.6 for $t t̅$ [ref] , then assuming a luminosity 100 $$, one can expect S/$√(B)$ about 3.5 for these mass ranges of $_1$ and $0_2$.
