Doublet-Triplet Splitting and Fat Branes
arXiv:hep-ph/0108002 · doi:10.1016/S0370-2693(01)01276-X
Abstract
We consider the doublet-triplet splitting problem in supersymmetric SU(5) grand unified theory in five dimensions where the fifth dimension is non-compact. We point out that an unnatural fine-tuning of parameters in order to obtain the light Higgs doublets is not required due to the exponential suppression of the overlap of the wave functions.
