Abstract: | The Standard Model predicts that Higgs bosons decay to bottom quarks a majorityof the time. The rate of this occurrence for Higgs bosons produced in association with a W or Z boson is measured with the CMS Run 2 dataset of proton-proton collisions at center-of-mass energy √s = 13 TeV. Data is selected based on leptons produced from the vector boson decay, the identification of b jets, and event kine- matics. Higgs decays resulting in two resolved jets or a single large jet are considered. Cross sections of the VH→bb process are measured differentially as a function of the vector boson transverse momentum and additional jet activity. The total yield of the VH→bb process is measured to be 1.15+0.22 −0.20 times the Standard Model expectation, while the differential cross sections agree with the Standard Model at the 5% level. Several possible improvements to the analysis are proposed. |
