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} 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. (Erratum appended, March 2014.)

Comments

20 pages, pdf included figures. Brief phenomenological analysis of additional scalar s-boson added. Erratum appended: an error in the Higgs-boson gluon-fusion production amplitude arising from the new colored states is corrected, resulting in stronger constraints on the model parameter space
