Relaxation of the Cosomological Constant
Abstract
We present a classical field theory which has a long epoch resembling the Friedmann universe despite the presence of a large negative cosmological constant. In its most plausible realization the model involves a massive third-rank antisymmetric-tensor gauge field. To be consistent with standard cosmology the mass must be extremely small and the only reasonable mechanism for generating it is a semiclassical tunneling effect.
