  Jet physics provides a powerful tool to investigate interaction properties of
quarks and gluons. These studies have been possible at an energy never
investigated before at LHC. In this proceedings we review the main
characteristics of experimental methods to measure jets in proton-proton
collisions at center-of-mass energies of 7 and 8 TeV. Novel methods are
expected to play an important role for searching new physics at center-of-mass
energy of 13 TeV.
