| dc.description | We report the issues of localization of various bulk fields on a brane in a curved background from a local field-theoretic viewpoint where a special attention is paid to a warp geometry in a general space-time dimension. We point out that spin 0 scalar field and spin 2 graviton are naturally localized on a brane with the exponentially decreasing warp factor, while spin 1/2 and 3/2 fermionic fields can be localized on the brane by introducing a bulk mass term with a 'kink' profile. {}For the localization of spin 1 vector field on the brane with the exponentially decreasing warp factor, it is shown that there are essentially two ways. One way is to appeal to the Dvali-Shifman method which is based on a peculiar feature of the non-abelian gauge dynamics such as bulk confinement, whereas the other way is to look for a solution of Einstein equations in such a way that the geometry has a property of confining the vector field to the brane by a gravitational interaction as in six dimensions. We point out that the latter way is more universal. | |
