Measurement of forward jets in proton--proton collisions at $\sqrt{s

We report on a measurement of the cross section of inclusive forward jets in proton-proton collisions at $\sqrt{s}$~=~7~TeV, with 3.14~pb$^{-1}$ integrated luminosity. Jets are reconstructed with the anti-$k_{T}$ algorithm (size $R =$~0.5) in the Hadronic Forward calorimeters at pseudorapidities 3.2 $< |\eta| <$ 4.7, in the transverse momentum range $p_T =$~35 -- 150~GeV/c. The measurement is compared to next-to-leading order perturbative Quantum Chromodynamics calculations, to \PYTHIA\ and \HERWIG\ parton shower event generators, as well as to the {\sc cascade} Monte Carlo.
