Description
Several measurements of jet final states are presented performed at
different center-of-mass energies and down to very low pt. The
simultaneous observation of several jets in the same event is
exploited to study for example the angular correlations of Mueller
Navelet jet topologies in order to search for the signature of BFKL
parton dynamics. But multi-jet measurements are also used to test
higher-order QCD effects, and by lowering the jet pt to the smallest
possible values the minijet production close to the factorization
limit is studied. Futhermore, diffractive final states are studied
identified either by the presence of rapidity gaps or the general
feature of central exclusive production. The single- and
double-diffractive cross section,. jet-gap-jet events as well as
exclusive pi+pi- production are presented.
