Measurement of the inclusive and differential Higgs boson production cross sections in the leptonic WW decay mode at $\sqrt{s} =$ 13 TeV

Measurements of the fiducial inclusive and differential production cross sections
of the Higgs boson in proton-proton collisions at √
s = 13 TeV are performed using events
where the Higgs boson decays into a pair of W bosons that subsequently decay into a
final state with an electron, a muon, and a pair of neutrinos. The analysis is based on
data collected with the CMS detector at the LHC during 2016–2018, corresponding to an
integrated luminosity of 137 fb−1
. Production cross sections are measured as a function of
the transverse momentum of the Higgs boson and the associated jet multiplicity. The Higgs
boson signal is extracted and simultaneously unfolded to correct for selection efficiency
and resolution effects using maximum-likelihood fits to the observed distributions in data.
The integrated fiducial cross section is measured to be 86.5 ± 9.5 fb, consistent with the
Standard Model expectation of 82.5 ± 4.2 fb. No significant deviation from the Standard
Model expectations is observed in the differential measurements.
