Abstract
The measurement of forward jet cross sections has been
suggested as a promising probe of
new small x parton dynamics
and
the question is
whether the new HERA data provide an indication of this.
In this paper the influence of resolved
photon processes has been investigated and it has been studied to
what extent the inclusion of such processes in addition to normal
deep inelastic scattering
leads to agreement with data.
It is shown that two DGLAP
evolution chains from the hard scattering process towards the proton
and the photon respectively,
are sufficient to describe effects observed
in the HERA data, which have been attributed to BFKL dynamics.
