Towards New Physics through Precision: Simultaneous Constraints on QCD Parameters and New Physics

The CMS measurements of inclusive jet production and of top quark-antiquark production in proton-proton collisions at the LHC at the center of mass energy of 13 TeV are used together with the data of inclusive deep inelastic scattering to extract the parton distribution functions in the proton, the top quark mass and the strong coupling constant. Using standard model predictions, the analysis at NNLO results in the most precise determination of the strong coupling constant at hadron collider. In an alternative analysis, the standard model is extended with effective couplings for 4-quark contact interactions, leading to the first simultaneous extraction of the standard model parameters and the Wilson coefficients of contact interactions using the LHC data.
