A Self-Tuning Solution of the Cosmological Constant Problem
arXiv:hep-th/0011006 · doi:10.1142/S0217732302008186
Abstract
We discuss the four-dimensional cosmological constant problem in a five-dimensional setting. A scalar field coupled to the SM forms dynamically a smooth brane with four-dimensional Poincare invariance, independently of SM physics. In this respect, our solution may be regarded as a self-tuning solution, free of any singularities and fine-tuning problems.
