Query: Localization of graviphoton and graviscalar on the brane   The question of whether the Kaluza-Klein (KK) graviphoton $h_{5\mu}$ and
graviscalar $h_{55}$ are localized or not on the brane is one of the important
issues. In this letter, we address this problem in five dimensions. Here we
consider the massless (zero-mode) propagations without requiring the
Z$_2$-symmetry on $h_{5\mu}$. We obtain the graviton $h_{\mu\nu}$, graviphoton,
and graviscalar exchange amplitudes on shell. We find that the graviscalar has
a tachyonic mass. It turns out that $h_{5\mu}$ admits the localized zero-modes
on the brane while $h_{55}$ does not have a localized zero-mode. This is
contrasted to the fact that the bulk spin-0 field has a localized zero-mode on
the brane but the bulk spin-1 field does not have a localized solution in five
dimensions.
