Gravity and electroweak symmetry breaking in a RSI/RSII hybrid model

We present a hybrid RSI/RSII model in which we both solve the hierarchy problem and produce a continuum of Kaluza-Klein graviton modes. In this model, four-dimensional gravity can be reproduced, and the radion mode can be stabilized. We then modify the hybrid gravity model to include SU(2)LxSU(2)RxU(1)B-L bulk gauge fields. Electroweak symmetry is broken by the choice of appropriate boundary conditions. By adjusting the size of one region of the extra dimension, we show that the S parameter can be decreased while protecting the ρ parameter from corrections. We find that as the S parameter is decreased by ∼60%, MZ' and MW' stay below 1800 GeV, protecting unitarity.
