Abstract: In CPV -MSSM a benchmark scenario (known in the literature as `CPX-scenario'), there exist a low enough light neutral Higgs ($h_1$, with $m_{h_1}\leq 60$ GeV) which is not ruled out by LEP, leaving a not probed 'hole' in $m_{h_1}-\tan{\beta}$ plane.
Many studies have been performed to probe the 'LEP hole' at the LHC. In particular we will discuss the associated Higgs productions, cascade production and pair productions at the LHC. These multi-channel analysis is worth studying to probe the 'hole' and to reconstruct the Higgs mass(es). Also charged Higgs lighter than top quark mass leads to non-trivial signal topologies unlike CPC-MSSM. The size of the hole is also depended on the soft SUSY breaking terms, $M_{\rm SUSY}$. We also try to find out the reach of $M_{\rm SUSY}$ to probe the 'hole' in the context of the LHC. It has been shown that with low to moderate accumulated luminosity, we will be able to probe the existing `hole' in the $m_{h_1}$-$\tan\beta$
