Query: Top and Higgs decays: looking for quantum SUSY signatures in hadron
  colliders   I present an updated discussion of the one-loop corrections to the standard
top quark decay, t-> W^+ b, and to the charged Higgs mode, t-> H^+ b, within
the framework of the MSSM. These higher order contributions to the top width
are compared with the direct top decays into 2 and 3 real SUSY particles. It
turns out that whereas the SUSY effects on t-> W^+ b add up to those from
standard QCD, they tend most likely to erase the conventional QCD corrections
to t-> H+ b. However, in the latter case the full (strong plus electroweak)
SUSY quantum effects are generally so large that the QCD corrections
effectively come out with the ``wrong sign''. A qualitatively distinct, and
quantitatively significant, ``quantum signature'' of that type might constitute
a most sought-after imprint of ``virtual'' Supersymmetry, which remains
sizeable enough even in the absence of any direct top decay into SUSY
particles. Similar considerations are made for the hadronic partial widths of
the Higgs bosons of the MSSM. While a first valuable test of these effects
could possibly be performed at the upgraded Tevatron, a more precise
verification would most probably be carried out in future experiments at the
LHC.
