  Processes involving heavy quarks in associated production, are usually
described in two factorisation schemes: one in which the heavy quark is treated
as an infinitely massive object, decoupled from QCD evolution, and one in which
it is treated on the same footing of a light quark.
  These two approaches only differ by the inclusion of mass suppressed terms or
in the resummation of a certain class of logarithms. In view of recent results,
in this talk, we present recent developments that extend a phenomenological
scheme, that tries to incorporate the best of both worlds, to \NLO in Monte
Carlo event generation.
