On the Perturbative Approach in the Randall-Sundrum Model
arXiv:0809.1378 · doi:10.1088/1126-6708/2008/10/035
Abstract
We study a SU(2)_L x U(1)_Y gauge theory in the Randall-Sundrum background, including electroweak symmetry breaking due to a brane-localized Higgs sector. We work in the decomposed four dimensional theory and treat the symmetry breaking effects as a perturbation. Although there is an exact approach, this method is widely used and quite intuitive. We extend existing studies by giving explicit analytical expressions in a covariant R_xi gauge, needed for loop calculations in the decomposed theory. The perturbative approach is also applied to fermions and a comparison of the gauge boson and fermion spectra with the exact results is presented, validating the perturbative method used in the literature.
