EXTRA-DIMENSIONS, CONFORMAL COUPLING AND HIGHER- DERIVATIVE THEORY IN THE BACKGROUND OF RICCI CONSTANT CURVATURE SPACETIME

摘要

Higher derivative gravity theory in d+ 1 dimensions with conformally non-minimal coupling scalar field and in the background of Ricci constant curvature spacetime is explored. We include the contribution of the ultra-light masses where some important features are revealed and particular case including the Gauss-Bonnet relation is discussed in some details.
