Probing Non-holomorphic MSSM via precision constraints, dark matter and LHC data

Understand

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 fine-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 $m_{\tilde {\mu_1}}$.
