A Way to Dynamically Overcome the Cosmological Constant Problem
Abstract
The Cosmological Constant problem can be solved once we require that the full standard Einstein Hilbert lagrangian, gravity plus matter, is multiplied by a total derivative. We analyze such a picture writing the total derivative as the covariant gradient of a new vector field (bmu). The dynamics of this bmu field can play a key role in the explanation of the present cosmological acceleration of the Universe.
