Higgs doublet as a Goldstone boson in perturbative extensions of the standard model

2011

The minimal supersymmetric standard model (MSSM) is extended by including an additional pair of constrained Higgs doublet superfields through which the electroweak symmetry is nonlinearly realized. The superpotential couplings of this constrained Higgs doublet pair to the MSSM Higgs doublet pair catalyze the later nontrivial vacuum expectation values. The mass spectrum of the Higgs scalars and Higgsino-gaugino sector is presented for several choices of supersymmetry (SUSY) breaking and Higgs superpotential mass parameters. The effect of the the additional constrained fields and multiple vacuum expectation values on the lowest mass neutral Higgs scalar production and decay is presented.

There are few robust solutions to the doublet-triplet splitting problem in supersymmetric GUT theories. One of the more promising solutions is the Higgs as pseudo-Goldstone boson mechanism. In its minimal implementation, such a solution places an additional restriction on the parameter space of the minimal supersymmetric standard model. A testable consequence of this constraint is an equation for tan β. We present this restriction and study its solutions in order to constrain the allowed parameter space. Thus the assumptions on the GUT scale Higgs sector should yield testable predictions for weak scale physics. If the SUSY parameters are measured then it should be possible to check the predictions, yielding insight into GUT scale physics.

Presentamos un modelo que genera el mecanismo de pseudo-Nambu-Goldstone a todo orden en teoria de perturbaciones para el problema de corrimiento de doblete-triplete en teorias supersimetricas de gran unificacion. Las simetrias globales del sector de Higgs son atribuidas al contenido no vectorial de Higgs, el cual es consistente con supersimetria no rota en un escenario de dimensiones extra planas y branas. Ademas, mostramos como en este modelo uno puede obtener un patron realistico de las masas y mezclas de fermiones del Modelo Estandar
