Quintessential Vanishing of the Cosmological Constant
arXiv:hep-ph/0005182
Abstract
We consider an effective field theory description of gravity coupled to a scalar field with volume-preserving diffeomorphism and Weyl invariances. The smallness of the cosmological constant is achieved when the potential of the scalar is extremely flat. This implies a possible relationship between the smallness and the quintessential sector of the cosmological constant.
