v3.2.5
Ten years after the announcement of the Higgs boson discovery by the ATLAS and CMS collaborations at the CERN LHC, the paradigm has changed from searching for a new resonance to performing precision measurements of its properties. The data sample collected by the two experiments so far allowed a large variety of measurements of the Higgs boson properties in all the main decay channels. This seminar presents the most recent measurements of Higgs boson production cross sections and couplings in the decay channel to a pair of W bosons. The measurements make use of the Run 2 LHC data collected by the CMS detector in proton-proton collisions at a center of mass energy of 13 TeV. The presented results cover the main Higgs boson production mechanisms and span a large variety of final states with 2, 3 and 4 charged leptons. The measurement of Higgs boson production cross sections in the Simplified Template Cross Sections framework will also be presented. The higher integrated luminosity and the newly developed analysis techniques allowed an unprecedented precision of the cross sections and couplings measurements, with a significant improvement with respect to the latest published results.
