We study extensions of the standard model with additional colored scalar fields which can couple directly to quarks. Natural suppression of flavor changing neutral currents implies minimal flavor violation, and fixes the scalars to transform as (8,2)1/2 under the SU(3)×SU(2)×U(1) gauge symmetry. We explore the phenomenology of the standard model with one additional (8,2)1/2 scalar, and discuss how this extension can modify flavor physics and the Higgs boson production rate at the LHC. Custodial SU(2) symmetry can be implemented for the octet scalars since they transform as a real color representation. Additional weak scale degrees of freedom needed for gauge unification are discussed.

- Colored resonant signals at the LHC: largest rate and simplest topology (2010, methodology): “As for the color-octet scalar states, we note that the renormalizable interactions between a color-octet scalar and two quarks are Yukawa type interactions, and the SM gauge invariant interactions require the scalar to be a doublet [ 54 ] under SU(2)L.”
