A Way to Dynamically Overcome the Cosmological Constant Problem
arXiv:0704.1802 · doi:10.1142/S0217751X08041359
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 (b_mu). The dynamics of this b_mu field can play a key role in the explanation of the present cosmological acceleration of the Universe.
