Dynamics in the Dark – Andrew Tolley

If Dark Energy is dynamical, it would indicate the existence of new physics beyond the standard model coupled to gravity. Just as supersymmetry and large extra dimensions have been invoked to solve the Higgs hierarchy problem, it seems natural that this new physics is tied to whatever resolves the cosmological constant hierarchy problem. I will discuss several proposals that have been put forward in this vein and their possible cosmological implications.
