Description
I will discuss a simple complete solution to both $\mu$ and the little hierarchy problems of the MSSM. This solution is achieved by combining MSSM with its two well known extensions. On the one side next-to-MSSM(NMSSM) can solve $\mu$ problem of the MSSM, but it is generically difficult to attain a tachyonic singlet required for this purpose, also addition of the singlet cannot increase significantly the prediction of the lightest CP-even Higgs mass (i.e., it does not solve the little hierarchy problem of the MSSM) in most of the region of parameter space. On the other side adding electroweak triplets (with non-zero hypercharge) to MSSM can solve the little hierarchy problem, but it creates an additional $\mu$ problem for the triplets. I will show that combination of the NMSSM and the model with SU(2) triplets may solve each others problems and I will discuss this combination in detail.
