T.E. Clark, S.T. Love, and T. ter Veldhuis
TL;DR
This paper explores a supersymmetric extension of the MSSM where electroweak symmetry is nonlinearly realized through additional constrained Higgs doublets, leading to novel Higgs and Higgsino-gaugino mass spectra and phenomenology.
Contribution
It introduces a new supersymmetric multi-Higgs model with non-linear electroweak symmetry breaking via constrained superfields, expanding the phenomenological landscape beyond the MSSM.
Findings
Different Higgs and Higgsino-gaugino mass spectra identified
Vacuum expectation values from constrained fields alter phenomenology
Model exhibits distinct experimental signatures compared to MSSM
Abstract
The electroweak symmetry is nonlinearly realized in an extension of the minimal supersymmetric standard model (MSSM) through an additional pair of constrained Higgs doublet superfields. The superpotential couplings of this constrained Higgs doublet pair to the MSSM Higgs doublet pair catalyze their vacuum expectation values. The Higgs and Higgsino-gaugino mass spectrum is presented for several choices of supersymmetry (SUSY) breaking and Higgs superpotential mass parameters. The additional vacuum expectation values provided by the constrained fields can produce a phenomenology quite different than that of the MSSM .
