Abstract

In this work we study implications of additional nonholomorphic soft breaking terms (\ensuremathμ^\ensuremath', At^\ensuremath', Ab^\ensuremath', and A_\ensuremathτ^\ensuremath') on the minimal supersymmetric extension of the standard model (MSSM) phenomenology. By respecting the existing bounds on the mass measurements and restrictions coming from certain B-decays, we probe reactions of the MSSM to these additional soft breaking terms. We provide examples in which some slightly excluded solutions of the MSSM can be made to be consistent with the current experimental results. During this, even after applying additional fine-tuning constraints, the nonholomorphic terms are allowed to be as large as hundreds of GeV. Such terms prove that they are capable of enriching the phenomenology and varying the mass spectra of the MSSM heavily, with a reasonable amount of fine-tuning. We observe that Higgsinos, the lightest stop, the heavy Higgs boson states A,H,H^\ifmmode±\else\textpm\fi, sbottom and stau exhibit the highest sensitivity to the new terms. We also show how the light stop can become nearly degenerate with top quark using these nonholomorphic terms.
