The stability and gravitational Newtonian limit of a modified Randall-Sundrum model
arXiv:1509.00365 · doi:10.1140/epjc/s10052-015-3873-z
Abstract
For a modified Randall-Sundrum model [Phys. Rev. D 88 (2013) 025048], the graviton equations are derived and the mass spectrum found. The latter includes a massless graviton and a continuum mass with a gap. There is no negative mass-squared in the spectrum, so the model is stable. The gravitational Newtonian limit is obtained with an exponentially suppressed modification from extra dimension.
