| Abstract: Possible anomalous couplings of the Higgs boson to vector bosons and fermions are studied in this document. The data are recorded by the CMS experiment at the LHC and corresponds to an integrated luminosity of 138 fb$ ^{-1} $ at a center-of-mass energy of 13 TeV. These measurements use Higgs boson candidates produced mainly in gluon fusion, electroweak vector boson fusion (VBF) and the associated production with a vector boson (VH) that subsequently decay to a pair of photons. Events are categorized based on matrix element techniques and multivariate discriminants. The CP properties in the Higgs boson couplings to gluons through a loop of heavy particles are studied, as well as the tensor structure of the interactions with two electroweak bosons, analyzing VBF and VH associated production. The results, interpreted as fractional contribution of each anomalous Higgs boson coupling to the total cross section of a process, are found consistent with the standard model expectations. | ||
