Conformal fixed point, Cosmological Constant and Quintessence
arXiv:hep-th/0210156 · doi:10.1103/PhysRevLett.90.231302
Abstract
We connect a possible solution for the ``cosmological constant problem'' to the existence of a (postulated) conformal fixed point in a fundamental theory. The resulting cosmology leads to quintessence, where the present acceleration of the expansion of the universe is linked to a crossover in the flow of coupling constants.
