Inclusive and exclusive production of scalar and pseudoscalar mesons
via gluon-gluon fusion is considered.
A new experimental test is proposed, which can probe the polarization
state of the gluons in exclusive production processes and check
the compatibility of the two-gluon exchange mechanism with the
properties of conventional Pomeron.
Key words:
diffraction, two-gluon exchange model
