Induced Electroweak Symmetry Breaking and Supersymmetric Naturalness

Understand

In this paper we study a new class of supersymmetric models that can explain a 125 GeV Higgs without fine-tuning.

• These models contain additional `auxiliary Higgs' fields with large tree-level quartic interaction terms but no Yukawa couplings.
• These have electroweak-breaking vacuum expectation values, and contribute to the VEVs of the MSSM Higgs fields either through an induced quartic or through an induced tadpole.
• The quartic interactions for the auxiliary Higgs fields can arise from either D-terms or F-terms.
