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.
