Abstract
We study the potential of hadron colliders in the search for
the pair
production of neutral Higgs bosons in the framework of the minimal
supersymmetric standard model. We perform a detailed signal
and
background analysis, working out efficient kinematical cuts for
the
extraction of the signal. The important role of squark loop
contributions to the signal is re-emphasized. If the signal
is
sufficiently enhanced by these contributions, it could even be
observable at the next run of the upgraded Tevatron collider
in the
near future. At the LHC the pair production of light and heavy
Higgs
bosons might be detectable simultaneously.
