  The LHC has started to explore the TeV energy regime, probing the SM beyond
LEP and Tevatron. We show how the dijet measurements at the LHC are able to
test certain sectors of the SM at an unprecedented level. We provide the best
bounds on all possible four-quark interactions and translate them into limits
on the compositeness scale of the quarks and gluons. We also provide
constraints on extra gauge bosons, Z', W' and G', and on new interactions
proposed to explain the present measurement of the forward-backward asymmetry
of the top.
