A Small Cosmological Constant and Backreaction of Non-Finetuned Parameters

High Energy Physics - Theory 2009-10-31 v4

Abstract

We include the backreaction on the warped geometry induced by non-finetuned parameters in a two domain-wall set-up to obtain an exponentially small Cosmological Constant Λ4\Lambda_4. The mechanism to suppress the Cosmological Constant involves one classical fine-tuning as compared to an infinity of finetunings at the quantum level in standard D=4 field theory.
