Enhanced Higgs diphoton rate and isospin symmetric Higgs boson

Abstract

Based on Ref.1, we introduce a model with an isospin symmetric Higgs boson and study the properties of this particle, including the enhancement of its diphoton decay rate. The predictions of the model relevant for future experiments are also discussed.
