- Abstract
- We present a self-tuning solution of the cosmological constant problem with one extra dimension which is curved with a warp factor. To separate out the extra dimension and to have a self-tuning solution, a three index antisymmetric tensor field is introduced with the 1/H-2 term in the Lagrangian. The standard model fields are located at the y = 0 brane. The existence [1] of the self-tuning solution (which results without any fine tuning among parameters in the Lagrangian) is crucial to obtain a vanishing cosmological constant in a 4D effective theory. The de-Sitter and anti-de-Sitter space solutions are possible. The de-Sitter space solutions have horizons. Restricting to the spaces which contain the y = 0 brane, the vanishing cosmological constant is chosen in the most probable universe. For this interpretation to be valid, the existence of the self-tuning solution is crucial in view of the phase transitions. In this paper, we show explicitly a solution in case the brane tension shifts from one to another value. We also discuss the case with the H-2 term which leads to one-fine-tuning solutions at most.
