The stability and gravitational Newtonian limit of a modified Randall-Sundrum model
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.Comment: 10 page
