| dc.description | We consider a generalized Randall Sundrum (RS) brane world scenario with a cosmological constant $Ω$ induced on the visible brane. We show that for $Ω<0$, resolution of the hierarchy problem requires an upper bound on the magnitude of $Ω$. The corresponding tension on the visible brane can be positive or negative. On the other hand, there is no such bound for $Ω>0$. 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. | |
