We consider the two-brane Randall-Sundrum (RS) model with bulk gauge fields. We carefully match the bulk theory to a 4D low-energy effective Lagrangian. In addition to the four-fermion operators induced by KK exchange we find that large negative S and T parameters are induced in the effective theory. This is a tree-level effect and is a consequence of the shapes of theW and Z wave functions in the bulk. Such effects are generic in extra dimensional theories where the standard model (SM) gauge… CONTINUE READING
