Query: Top quark decays into neutral Higgs bosons and gluon in the MSSM   Flavour changing neutral decays of the top quark are know to be extremely
suppressed in the SM. This is especially so for the top quark decay into the SM
Higgs boson, whose rate is less than 10^-13. However, it turns out that the
decay modes t->c h, with h= h^0,H^0,A^0 any of the MSSM neutral Higgs bosons,
can be much more gifted. In particular, the rate into the lightest CP-even
Higgs boson h^0 -- which is an accessible decay mode across the whole MSSM
parameter space -- is generally higher than the decay into glue, t->c g, even
though the latter can also be considerably augmented in the MSSM. Our general
conclusion is that the Higgs channel t->c h^0 can be the ``gold-plated'' top
quark FCNC decay mode in the MSSM with rates that can reach 10^-4, i.e. already
at the visible level for both LHC and LC.
