Non-standard supersymmetry breaking and Dirac gaugino masses without supersoftness

TL;DR

This paper explores models with non-standard supersymmetry breaking, including Dirac gaugino masses, arising from F-term breaking with unique suppression, leading to new features and decoupling in the Higgs sector.

Contribution

It introduces a framework where supersymmetry breaking terms originate from F-term operators with $1/M^3$ suppression, generalizing supersoftness and decoupling the $$ term from Higgs masses.

Findings

Supersoft properties are not generic but can be fixed points of RG flow.

The $$ term is replaced by three parameters, decoupling Higgs potential from Higgsino masses.

Induces flavor-violating scalar interactions in the MSSM.

Abstract

I consider models in which non-standard supersymmetry breaking terms, including Dirac gaugino masses, arise from F-term breaking mediated by operators with a $1/M^3$ suppression. In these models, the supersoft properties found in the case of D-term breaking are absent in general, but can be obtained as a special case that is a fixed point of the renormalization group equations. The $\mu$ term is replaced by three distinct supersymmetry-breaking parameters, decoupling the Higgs scalar potential from the Higgsino masses. Both holomorphic and non-holomorphic scalar cubic interactions with minimal flavor violation are induced in the supersymmetric Standard Model Lagrangian.
