Constraints on the scalar sector of the renormalizable coloron model

Abstract

The renormalizable coloron model is the minimal extension of the standard model color sector, in which the color gauge group is enlarged to SU(3) 1c×SU(3)2c. In this paper we discuss the constraints on this model derived from the requirements of vacuum stability, tree-level unitarity, and electroweak precision measurements from LHC measurements of the properties of the observed Higgs-like scalar boson and from LHC limits on additional Higgs-like bosons decaying to dibosons. The combination of these theoretical and experimental considerations strongly constrains the allowed parameter space. © 2013 American Physical Society.
