Özet

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/√se-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. © 2010 IACS.
