Abstract
We consider a generalized Randall Sundrum (RS) brane world scenario with a cosmological constant
induced on the visible brane. We show that for
< 0, resolution of the hierarchy problem
requires an upper bound on the magnitude of
. The corresponding tension on the visible brane
can be positive or negative. On the other hand, there is no such bound for
> 0. However, in this
case, the resolution of the hierarchy problem along with the tuning of the value of the cosmological
constant to its observed value closed to +10−124 (in Planck units) naturally lead to the tuning of
the modulus to a small value of inverse Planck length as estimated in the original RS scenario.
