Summary
We have discussed single and central diffractive production of c¯c pairs in
the Ingelman-Schlein model. In these calculations we have included diffrac-
tive parton distributions obtained by the H1 collaboration at HERA and
absorption effects neglected in some early calculations in the literature. The
absorption effects which are responsible for the naive Regge factorization
breaking cause that the cross section for diffractive processes is much smaller
than that for the fully inclusive case, but could be measured at RHIC and
LHC by imposing special condition on rapidity gaps. We discuss also a fully
exclusive diffractive production of c¯c. It was advocated recently that the
cross section ...
