We consider a 5-dimensional brane world model with a single brane which is
distinct from the well known Randall-Sundrum model. We discuss the similarities
and differences between our brane model and the Randall-Sundrum brane model. In
particular we focus on the localization of 5D fields with different spins --
spin 0, spin 1/2, spin 1 -- to the brane, and a self-consistent mass generation
mechanism. We find that the brane model studied here has different (and in some
cases superior) localization properties for fields/particles with different
spins to the brane, as compared to the original 5-dimensional brane models. In
addition this alternative 5D brane model exhibits a self generation mechanism
which recalls the self-consistent approach of Nambu and Jona-Lasinio.Comment: 25 pages, no figures. Version matches published version, minor
