| Measurements of differential Higgs boson production cross sections in the leptonic WW decay mode at $\sqrt{s} = $ 13 TeV | ||
| CMS Collaboration | ||
| September 2019 | ||
| Abstract: Measurements of differential production cross sections of the Higgs boson in pp collisions at $\sqrt{s} = $ 13 TeV are performed using events where the Higgs boson decays into a pair of W bosons which subsequently decay into an electron, a muon, and a pair of neutrinos. The analysis is based on data collected by the CMS detector at the LHC in 2016, 2017, and 2018, and corresponds to an integrated luminosity of 137 fb$^{-1}$. Production cross sections with respect to the transverse momentum of the Higgs boson and the number of hadronic jets are considered. Higgs boson signal spectra are extracted and simultaneously unfolded to correct for selection efficiency and resolution effects by means of maximum likelihood fits to the observed event distributions. | ||

| Summary |
| Differential and integrated fiducial cross sections for the Higgs boson production have been measured using the ${\mathrm{H}\to\mathrm{W}{}\mathrm{W}\to\mathrm{e}\nu\mu\nu}$ decay. The measurements have been performed with pp collision data sets recorded by the CMS detector at a center-of-mass energy of 13 TeV in 2016, 2017, and 2018, corresponding to a total integrated luminosity of 137 fb$^{-1}$. Differential cross sections with respect to the Higgs boson transverse momentum and the number of jets produced in association are considered, in a fiducial phase space defined to match the experimental kinematic acceptance. The cross sections are extracted through a simultaneous template fit to kinematic distributions of the signal candidate events finely categorized to maximize the sensitivity to Higgs boson production. The measurements are compared to SM theoretical calculations using POWHEG and MadGraph5+MCatNLO generators. The integrated fiducial cross section is measured to be 85.0$^{+9.9}_{-9.3}$ fb, consistent with the SM expectation. |
