Abstract
Abs We show that the Standard Model can be formulated in a warped extra dimension with a soft wall. The infrared boundary is replaced with a smoothly varying dilaton field that provides a dynamical spacetime cutoff, generalising the usual hard-wall warped dimension. This allows a more general spacing for the Kaluza-Klein mass spectrum of bulk fields, including the possibility of Regge-like behaviour. Moreover the usual features of hard-wall setups can be reproduced where electroweak symmetry is now broken with a bulk Higgs condensate.
