Abstract

We argue that the familiar gauge hierarchy between the fundamental Planck scale M_Pl and the electroweak scale M_W, can be naturally explained in higher dimensional theories with relatively large radii (R_c > 1/M_Pl) extra dimensions. In particular, we show that it is possible that the electroweak Higgs mass at high energies is of the order of M_Pl, but radiative corrections drive it to an infrared stable fixed-point ∼ M_W at low energies thus inducing a large hierarchy without any fine tuning of parameters.
