Effective Gauss-Bonnet Interaction in Randall-Sundrum Compactification
Jihn E. Kim🇰🇷 · Bumseok Kyae🇰🇷 · Hyun Min Lee🇰🇷
Abstract
The effective gravitational interaction below the Planck scale in the Randall-Sundrum world is shown to be the Gauss-Bonnet term. In this theory we find that there exists another static solution with a positive bulk cosmological constant. Also, there exist solutions for positive visible sector cosmological constant, which are needed for a later Friedman-Robertson-Walker universe.
