  The implications of the latest measurement of the branching fraction of B($
b\rightarrow s \gamma $) of b hadrons, which is another signature of New
Physics beyond Standard Model is presented here. The quark transitions $ b
\rightarrow s $, $ b \rightarrow d $ do not happen at tree level in the
Standard Model as the Z boson does not couple to quarks of different flavour.
In this work the present bounds on the quark transition $ b \rightarrow s $
within the constrained minimal supersymmetric extension of the Standard Model
(CMSSM), in which there are three independent soft SUSY breaking parameters $
m_{0} $, $ m_{1/2} $ and $ A_{0} $ is illustrated. The recent constraint on B($
b\rightarrow s \gamma $), B($ b_{s}\rightarrow \mu^{+}\mu^{-}$), the recently
measured value of Higgs mass at LHC, $ M_{h} $, the value of $\theta_{13}$ from
reactor data and the Higgs branching ratios set very strong constraints on New
Physics models, in particular supersymmetry. A new epoch for this research has
begun since the Large Hadron Collider beauty (LHCb) experiment started
affording data for various observables for these decays. The results presented
here in mSUGRA/CMSSM models may gain access to supersymmetry even at scales
beyond the direct reach of the LHC and the susceptibleness to test these
theories at the next run of LHC is also explored.
