Low-x QCD studies with forward jets in proton-proton collisions at 14 TeV
Abstract
The Large Hadron Collider will provide hadronic collisions at energies in the multi-TeV range, never explored before. The parton fractional momenta probed at such energies can be as low as x~2pT/(s) e(-y)~10-5 at large rapidities y, opening up attractive opportunities for low-x QCD studies. The combination of the CMS HF (3<|η|<5) and CASTOR (5.1<|η|<6.6) calorimeters allows one, in particular, to reconstruct very forward jets. We present generator-level studies of the CMS capabilities to measure the single inclusive forward jet spectrum and forward-backward (Mueller-Navelet) dijets in p-p collisions at 14 TeV. Both observables are sensitive to low-x gluon densities and non-linear QCD evolution.
