Higgs boson anomalous couplings using the di-photon channel with CMS experiment.

Studies of CP violation and anomalous couplings of the Higgs boson to vector bosons are presented. The data were acquired by the CMS experiment at the LHC and correspond to an integrated luminosity of $138 fb^{-1}$ at a proton-proton collision energy of 13 TeV. The kinematic effects in the Higgs boson's two-photons decay and its production in association with two jets (Vector-Boson-Fusion, VBF) are analyzed, using a full detector simulation and matrix element techniques or, alternatively, multivariate algorithms to identify the production mechanisms and to increase sensitivity to the Higgs boson tensor structure of the interactions. A simultaneous measurement is performed for multiple Higgs boson couplings to electroweak vector bosons (HVV).
