Description

We consider the decay of a massive top quark accompanied by the emission of a ''hard'' photon or gluon. We find that the hard-photon bremsstrahlung increases the width of the top quark by 1% or so while the hard-gluon contribution can be as large as 30%. We also consider the possibility of using the first process to measure precisely the mass of the top quark or some Kobayashi-Maskawa mixing-matrix parameters
