### Description

In this analysis we explore the phenomenological constraints of models
with non-holomorphic soft SUSY breaking terms in a beyond the MSSM scenario
having identical particle content. The model referred as NHSSM shows various
promising features like the possibility of a strong reduction in electroweak fin
e-tuning even for a scenario of a heavy higgsino type of LSP, a fact that is unavailable in pMSSM models. The other important aspect is satisfying the muon $g-2$ data even for a small
$\tan\beta$ via a small value of coupling $A_\mu'$ associated with the tri-linear non-holomorphic soft term. Thus, a large SUSY contribution to muon $g-2$ is possible
even for a significantly large smuon mass $m_{\tilde {\mu_1}}$. The Higgs mass radiative corrections are contributed by both the holomorphic and non-holomorphic trilinear soft parameters $A_t$ and $A_t'$, thus diluting the requirement to have a larger $A_t$
to satisfy the Higgs mass data. The model also provides with valid parameter space
satisfying the constraint of $B \rightarrow X_s +\gamma$ for large values of
$\tan\beta$, a scenario unfavourable in pMSSM.
