Forward Jets and Forward-Central Jets at CMS

We report on cross section measurements for inclusive forward jet production and for the simultaneous production of a forward and a central jet in $\sqrt{s} = $7 TeV $pp$-collisions. Data collected in 2010, corresponding to an integrated luminosity of 3.14 pb$^{-1}$, is used for the measurements. Jets in the transverse momentum range p$_{T}$ = 35 - 140 GeV/c are reconstructed with the anti-k$_{T}$(R = 0.5) algorithm. The extended coverage of large pseudo-rapidities is provided by the Hadronic Forward calorimeter (3.2 $< \eta <$ 4.7), while central jets are limited to $\eta <$ 2.8, covered by the main detector components. The two differential cross sections are presented as a function of the jet transverse momentum. Comparisons to next-to-leading order perturbative calculations, and predictions from event generators based on different parton showering mechanisms ({\sc pythia} and {\sc herwig}) and parton dynamics ({\sc cascade}) are shown.
