Sumario:Measurements of the double-differential inclusive jet cross sections and triple-differential top quark-antiquark pair production cross sections have been performed at the center of mass energy of 13 TeV by the CMS Collaboration. The results of these measurements are used together with the data of inclusive deep inelastic scattering to extract the proton parton distribution functions, the top quark mass and the strong coupling constant. Using standard model predictions, the analysis results in the most precise determination of the strong coupling constant using LHC jet data. In an alternative analysis, the standard model is extended with effective couplings for 4-quark contact interactions, leading to a first-ever simultaneous extraction of the standard model parameters and the contact interactions' Wilson coefficients using LHC data.
