pomeron, and hence are necessarily close to mass shell. The basic
diagram which illustrates this scheme is shown
in~Fig.\,\ref{fig:dijet}, where here the photon is probing the quark
structure of the pomeron. This interpretation does not allow direct
couplings between the pomeron and off~shell partons.

A similar expression can be formed for interactions such as those
of~Fig.\,\ref{fig:3jets} where more than two final state partons are produced.

\caption{Constraints on struck quark virtuality from pseudo-rapidity
cuts used in early ZEUS
experiments\,\cite{Derrick:1994ze}. The~$k^2_{min}$ data corresponds
to Ref.\,\cite{Ellis:1996cg} (without the small angle approximation
used in the original calculation).\label{table:ervirtuality} }
\end{table}
 
and therefore the result is not sensitive to strong rapidity cuts. For
a wide range of HERA phase space, the diagram of~Fig.\,\ref{fig:2glue}
is expected to provide the main contribution to the pomeron structure.
