Description
The internal structure of jets produced in proton-proton collisions at 7 TeV centre-of-mass energy
provides a direct test of QCD calculations of gluon and quark radiation, as well as having sensitivity
to hadronisation and underlying event. The transverse energy distribution around the jet core has been measured,
as well as the fragmentation of a jet into charged particles. Jet shapes - including the jet mass -
and jet substructure have the potential to identify jets coming from massive, boosted particles decaying
hadronically. Techniques have also been developed for reducing the sensitivity of jet physics to soft
QCD and to multiple proton-proton collisions. A selection of such variables is also measured and compared
to a range QCD calculations and phenomenological models.
