Constraints on the Scalar Sector of the Renormalizable Coloron Model    [PDF]

R. Sekhar Chivukula, Arsham Farzinnia, Jing Ren, Elizabeth H. Simmons
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} x SU(3)_{2c}. In this paper we discuss the constraints on this model derived from the requirements of vacuum stability, tree-level unitarity, electroweak precision measurements, and from LHC measurements of the properties of the observed Higgs-like scalar boson. The combination of these theoretical and experimental considerations strongly constrains the allowed parameter space.
