  Central exclusive diffractive (CED) production of meson resonances
potentially is a factory producing new particles, in particular a glueball. The
produced resonances lie in trajectories with vacuum quantum numbers,
essentially on the pomeron trajectory. A tower of resonance recurrences, the
production cross section and the resonances widths are predicted. A new feature
is the form of the non-linear pomeron trajectory, producing resonances
(glueballs) with increasing widths. At LHC energies, in the nearly forward
direction the $t$-channel both in elastic, single or double diffraction
dissociation as well as in CED is dominated by pomeron exchange (the role of
secondary trajectories is negligible, however a small contribution from the
odderon may be present).
