We discuss both MSSM and NMSSM scenarios in which the lightest Higgs boson with $m_h=98$~GeV is consistent with the small excess ($\sim 2.3 \sigma$) observed at the LEP in $e^+ e^-\rightarrow Zh$, with $h \rightarrow b {\bar b}$ process and the heavier Higgs boson of mass close to 125~GeV as the observed candidate of the SM Higgs like particle at the LHC. We show the allowed regions in the non-decoupling Higgs zone of MSSM parameter space which are consistent with several low energy constraints coming from heavy flavour physics, latest experimental data on Higgs signals and lower limit on superparticle masses from 7~TeV and 8~TeV LHC run. We also implement the constraints from the relic density of the cold dark matter as obtained from the recent PLANCK data. Additionally, we discuss the possibility of observing the light Higgs boson of mass 98~GeV at the 14~TeV LHC run via $pp \rightarrow V h$, with $h \rightarrow b \bar b$ using the technique of jet substructure. Our analysis shows that at 14~TeV LHC run with 300 ${\rm fb}^{-1}$ luminosity the signal efficiency of such a light Higgs boson is at most 2.5$\sigma$. Finally, we make a comment on the prospect of proposed $e^+ e^-$ ILC to discover/exclude this light Higgs boson.

The constraints from the $B_s →μ^+ μ^-$(2$σ$) [ref] and $b →s γ$(3$σ$) [ref] decays are also indicated: [equation] The strips of red dots indicate the cosmologically compatible dark matter relic density regions, satisfying WMAP [ref] /PLANCK [ref] data,[The limits correspond to a 5$σ$ range of the PLANCK data that accommodates well the WMAP provided range.] [equation] They are usually classified into the following four regions[We will ignore here the so-called bulk-annihilation region characterized by LSP pair annihilation via t-channel slepton exchange since it occurs for a smaller $m_1/2$ zone that is excluded by the Higgs mass data.]. 1.

However, such a possibility is confined to a very fine-tuned region of the parameter space, which is essentially ruled out by the direct search limits on the lightest Higgs $h$ and the pseudo-scalar Higgs $A$ and other experimental constraints from flavor physics [ref] .

In turn this explains the difficulty of a simple enough description of the related phenomenology as well as the extended literature on the subject.[For a partial list of recent references, see [ref] .] The purpose of this work is to outline a possible overall strategy to search for signs of the $CP$-even extra-states of the NMSSM Higgs sector.
