  We explore the phenomenology of scalar fields in the adjoint representation
of SM gauge groups. We write a general set of dimension 5 effective operators
in which SM adjoint scalars couple to pairs of standard model bosons. Using
these effective operators, we explore new possible decay channels of a scalar
color octet into a gluon and a Z boson/ gluon and a photon. We recast several
analyses from Run I of the LHC to find constraints on an a scalar octet
decaying into these channels, and we project the discovery potential of color
octets in our gluon+photon channel for the 14 TeV run of LHC.
