Probing QCD with the ATLAS detector

The production of inclusive jets and di-jets at hadron colliders provides a stringent test of perturbative QCD at the highest energies. The process can also be used to probe the gluon density function of the proton. The ATLAS collaboration has measured the inclusive jet production cross section in 20.3 /fb of data collected at a center-of-mass energy of 8TeV and in 3.2 /fb of data collected at a center-of-mass energy of 13TeV. The measurements have been performed differentially in jet rapidity and transverse momentum. The collaboration also presents a measurement of the di-jet cross section at a center-of-mass energy of 13TeV as a function of the di-jet mass and rapidity-difference. The results have been compared with state-of-the-art theory predictions at NLO in pQCD, interfaced with different parton distribution functions. Moreover, we present the measurements of transverse energy-energy correlation allowing to test the renormalization group equation and extracting the strong coupling constant.
