Using Higgs Boson Production in Association with Three Jets via Gluon Fusion at the LHC to Investigate the CP Properties of the Higgs Boson
Abstract
A neutral Higgs boson Φ with general scalar and pseudoscalar couplings and accompanying jets can be efficiently produced via gluon fusion through heavy-quark loops in high-energy hadronic collisions. We present integrated cross sections and kinematic distributions for the production of a generic Higgs boson Φ in association with three jets, pp → Φjjj, at order αs5. We include the full mass dependence of the top- and bottom-quark loop contributions, combined coherently so that their interference is retained. Earlier finite-mass calculations of Φ+3 jets with bottom-quark loops and CP-odd or CP-mixed couplings were restricted to gg → gggΦ; we include the complete set of partonic subprocesses, and find that the quark-containing channels supply close to one half of the pseudoscalar three-jet cross section at tanβ=1. In a Type-II two-Higgs-doublet model the bottom-quark loop comes to dominate the rate as tanβ is increased, so that the cross section is non-monotonic in tanβ. Comparing against the heavy-top effective theory and its form-factor-improved version, we show that the effective description fails in the hard tails of the transverse-momentum and dijet-mass distributions, while the third-jet centrality z⋆ and the rapidity separation of the two leading jets are largely insensitive to the heavy-quark treatment. We further study the multi-jet azimuthal correlation Φ2, built from the jet momenta on the two sides of the Higgs boson in rapidity, and find that the bottom-quark contribution modifies its shape even for a state of definite CP. For a CP-mixed state the interference of the two couplings adds a sin2Φ2 term, which a simple counting asymmetry isolates and which no CP eigenstate can produce. Numerical results are presented for the LHC at √s=13.6TeV and mΦ=125.2GeV.

AB - A neutral Higgs boson Φ with general scalar and pseudoscalar couplings and accompanying jets can be efficiently produced via gluon fusion through heavy-quark loops in high-energy hadronic collisions. We present integrated cross sections and kinematic distributions for the production of a generic Higgs boson Φ in association with three jets, pp → Φjjj, at order α_s^5. We include the full mass dependence of the top- and bottom-quark loop contributions, combined coherently so that their interference is retained. Earlier finite-mass calculations of Φ+3 jets with bottom-quark loops and CP-odd or CP-mixed couplings were restricted to gg → gggΦ; we include the complete set of partonic subprocesses, and find that the quark-containing channels supply close to one half of the pseudoscalar three-jet cross section at tanβ=1. In a Type-II two-Higgs-doublet model the bottom-quark loop comes to dominate the rate as tanβ is increased, so that the cross section is non-monotonic in tanβ. Comparing against the heavy-top effective theory and its form-factor-improved version, we show that the effective description fails in the hard tails of the transverse-momentum and dijet-mass distributions, while the third-jet centrality z^⋆ and the rapidity separation of the two leading jets are largely insensitive to the heavy-quark treatment. We further study the multi-jet azimuthal correlation Φ_2, built from the jet momenta on the two sides of the Higgs boson in rapidity, and find that the bottom-quark contribution modifies its shape even for a state of definite CP. For a CP-mixed state the interference of the two couplings adds a sin2Φ_2 term, which a simple counting asymmetry isolates and which no CP eigenstate can produce.
