Calculating Boosted Higgs Boson Production as a Function of Couplings to Top Quarks, Bottom Quarks, and Vector Bosons

In 2012 the Higgs boson was discovered at the Large Hadron Collider (LHC) at
CERN. Measurements of the Higgs boson’s mass and couplings to other particles are now a high
priority for particle physicists. In particular, deviations from the expected couplings would
appear as changes to the Higgs cross-section. It is therefore important to analyze the cross
sections in terms of the coupling parameters. In this study, Higgs production rates in 13 TeV
proton-proton collisions were calculated with a Monte Carlo-based program and event generator
named VBFNLO. The dependence on the Higgs couplings to top quarks, bottom quarks, and
vector bosons was parameterized with a polynomial fit. Because boosted Higgs production is
expected to result in a cleaner signature for precision measurements, the fits were performed in
both inclusive and boosted samples. Overall, these fits manifest the clear relations between the
Higgs cross section and the couplings of the fundamental particles.
