Electroweak and QCD Physics at CMS

We present recent standard model measurements performed by the CMS experiment at the LHC, using proton-proton collision data at center-of-mass energies of 7, 8, and 13 TeV. Standard model processes involving jets and electroweak gauge bosons span many orders of magnitude in production cross section. Measurements of high-rate processes provide stringent tests of the standard model and help tune the theoretical predictions and Monte Carlo simulations. Thanks to the unprecedented energy and the integrated luminosity provided by the LHC, rare electroweak processes can also be measured for the first time, such as triboson production and vector boson production through vector boson scattering. In addition, new physics phenomena, even beyond the LHC reach, may manifest as enhancements in the multiboson production rate at high energy. Limits on such possible scenarios are set using an effective field theory with anomalous electroweak gauge couplings
