With an emphasis on the mass scale of new physics, I will discuss
several well motivated models of particle interactions that give rise
to testable signatures at the CERN Large Hadron Collider (LHC), as
well as complimentary signatures that are being probed by a collection
of ongoing dark matter (DM) experiments. In particular, I will discuss
the present and future prospects for detecting signals of
supersymmetry at the LHC within the framework of supergravity and
strings, and the interesting new collider physics of a recently
proposed class of models which admit dark matter and dark charge
through a gauge invariant dark sector. Dark matter detection
prospects, such as annihilations in the galactic halo and scattering
in terrestrial experiments will also be discussed. I will aim to
provide a bridge between these different model classes via the concept
of hidden symmetries, which as I will describe, exist in a very broad
class of new models of fundamental particle interactions.
