Mass of the Dilaton and the Cosmological Constant
Abstract
One might raise the question if the gravitational scalar field (dilaton) mediates a finiterange force between local objects that behaves globally like a massless field in conformity with the scenario of a decaying cosmological constant. We obtain a nonnegative answer to this question by carrying out a detailed analysis of the fieldtheoretical quantization procedure taking into account the observationally required suppression of the vacuum energy which constitutes a part of the cosmological constant.
