Flavor changing neutral currents, an extended scalar sector, and the Higgs production rate at the CERN Large Hadron Collider
Flavor changing neutral currents, an extended scalar sector, and the Higgs production rate at the CERN Large Hadron Collider
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 $(\mathbf{8},\mathbf{2}{)}_{1/2}$ under the $SU(3)\ifmmode\times\else\texttimes\fi{}SU(2)\ifmmode\times\else\texttimes\fi{}U(1)$ gauge symmetry. We explore the phenomenology of the standard model …
