Query: Top Mode Standard Model in Six Dimensions   We construct a top-mode standard model where the third generation fermions
and the SU(2)_L \times U(1)_Y gauge bosons are put on a 6-dimensional
brane(5-brane) with the extra dimensions compactified on the TeV
scale(R_5^{-1}=R_6^{-1} \equiv R^{-1}= 1-10 TeV), while only the gluons live in
a compactified 8-dimensional bulk(R_7^{-1}=R_8^{-1} \equiv \Lambda \gg
R^{-1}).On the 5-brane, Kaluza-Klein (KK) modes of the bulk gluons give rise to
induced four-fermion interactions which, combined with the gauge interactions,
are shown to be strong enough to trigger the top quark condensate, based on the
dynamics of 6-dimensional gauged Nambu-Jona-Lasinio (NJL) model. Moreover, we
can use a freedom of the brane positions to tune the four-fermion coupling
close to the critical line of 6-dimensional gauged NJL model, so that the gap
equation can ensure the top condensate on the weak scale while keeping other
fermions massless. There actually exists a scale (``tMAC scale''), \Lambda_{\rm
tM} = (7.8-11.0) R^{-1}, where the running gauge couplings combined with the
induced four-fermion interactions trigger only the top condensate while no
bottom and tau condensates. Furthermore, presence of such explicit four-fermion
interactions enables us to formulate straightforwardly the compositeness
conditions at \Lambda=\Lambda_{\rm tM}, which, through the
renormalization-group analysis, yields a prediction of masses of the top quark
and the Higgs boson, m_t = 177 - 187 GeV and m_H = 183 - 207 GeV.
