Dual description of the brane world cosmological constant with HMNPQ

Abstract

We present a short review of the recent 5D self-tuning solution of the cosmological constant problem with a 1/H2 term and present the dual description of the solution. In the dual description, we show that the presence of the coupling of the dual field (σ) to the brane, which is a bit different from the original theory, maintains the self-tuning property.
