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 at low energies thus inducing a large hierarchy without any fine tuning of parameters.- field theory: scalar
