Hard diffraction is not limited to jet
production. As mentioned earlier, there is already evidence for
diffractive W boson production [13]. There is now preliminary
evidence for diffractive b quark and J/
production as
well [28].
It is plausible that
every state below mass threshold
can be produced diffractively, so diffractive production
of Higgs bosons and top quarks
is not out of the question.
The FPD combined with the excellent particle identification of
the upgraded DØ detector will allow searches for a large
range of hard diffractive final states.
Combining the information from different
diffractive searches will allow the determination of the
quark and gluon content of the pomeron, as well as testing
whether it behaves like a universal object with a consistent
structure.
