Abstract
We present the results of recent work on the central exclusive production of
meson pairs. We concentrate on the case of flavour-singlet pseudoscalar mesons
eta, eta' and show that the central exclusive process, as modelled using a
recent novel application of the 'hard exclusive' perturbative formalism, is
potentially highly sensitive to the size of the gluon content of these states.
We also discuss the exclusive production of meson pairs in the lower mass
region, and present the first results of the new Dime Monte Carlo.
