Abstract:
In this study we examine how adding new colored states effects Higgs
production through gluon fusion. We consider general SU(3)_c
representations of scalars, fermions, and vectors and examine the
effects of adding one or more of these particles, on gg -> h.
We also examine the phenomenology and constraints of these new
colored states. We show that these new colored states can reduce or
enhance Higgs production and in some cases these new physics effects
can conspire to hide one another, leaving the Higgs production cross
section unchanged from the rate predicted by the SM. Thus one can not
use measurements of the Higgs production cross section alone to
unambiguously apply constraints on new colored states, but when combined
with direct search constraints can be a powerful handle in uncovering or excluding
the existence of new colored particles.
