Update on the Pyramid Scheme

TL;DR

This paper reviews recent developments in the Pyramid Scheme, a theoretical model aiming to be consistent with LHC physics, featuring unique gauge interactions and Higgs mass enhancements similar to the NMSSM.

Contribution

It introduces a novel approach to the Pyramid Scheme with multiple singlet fields and a strongly coupled gauge sector, differing from traditional unification constraints.

Findings

Enhanced Higgs mass contributions similar to NMSSM

Preference for small tan β in the model

Distinct constraints from perturbative unification

Abstract

We summarize recent work in which we attempt to make a consistent model of LHC physics, from the Pyramid Scheme. The models share much with the NMSSM, in particular, enhanced tree level contributions to the Higgs mass and a preference for small tan {\beta}. There are 3 different singlet fields, and a new strongly coupled gauge theory, so the constraints of perturbative unification are quite different. We outline our general approach to the model, which contains a Kahler potential for three of the low energy fields, which is hard to calculate. Detailed calculations, based on approximations to the Kahler potential, will be presented in a future publication.
