Virtual corrections to Higgs boson pair production in the large top quark mass limit
نویسندگان
چکیده
We calculate the three-loop matching coefficient CHH , required for a consistent description of Higgs boson pair production in gluon fusion through next-to-next-toleading order QCD in the heavy top quark approximation. We also compute the gg → HH amplitude in mt → ∞ approximation in the full theory and show its consistency with an earlier computation in heavy-top effective theory. ∗On leave of absence from Department of Physics and Astronomy, Johns Hopkins University, Baltimore, MA, USA

Higgs boson pair production at the LHC: top-quark mass effects at next-to-leading order
Higgs boson pair production is considered at next-to-leading order with special emphasis on the effect of a finite top quark mass. It is shown that, unlike for single-Higgs boson production, power-suppressed corrections are numerically important.
متن کاملTo the Decay of an Intermediate–mass Higgs Boson into Two Photons∗
The QCD correction of O(α s ) to the decay of the Standard Model Higgs boson into two photons is presented. We consider the contribution coming from diagrams with a heavy top quark as virtual particle. The first three terms of the expansion in the inverse top mass is calculated. Expressing the result through the on-shell top mass Mt, we find large coefficients for the power-suppressed terms whe...
متن کاملAn approximation for NLO single Higgs boson inclusive transverse momentum distributions in hadron-hadron collisions
In the framework of the gluon-gluon fusion process for Higgs boson production there are two different prescriptions. They are given by the exact process where the gluons couple via top-quark loops to the Higgs boson and by the approximation where the top-quark mass mt is taken to infinity. In the latter case the coupling of the gluons to the Higgs boson is described by an effective Lagrangian. ...
متن کاملBeyond Heavy Top Limit in Higgs Boson Production at Lhc
QCD corrections to inclusive Higgs boson production at the LHC are evaluated at next-tonext-to leading order. By performing asymptotic expansion of the cross section near the limit of infinitely heavy top quark we obtained a few first top mass-suppressed terms. The corrections to the hadronic cross sections are found to be small compared to the scale uncertainty, thus justifying the use of heav...
متن کاملVirtual three-loop corrections to Higgs boson production in gluon fusion for finite top quark mass
In this letter we present the three-loop virtual corrections to the Higgs boson production in the gluon fusion channel where finite top quark mass effects are taken into account. We perform an asymptotic expansion and manage to evaluate five terms in the expansion parameter M2 H/M 2 t . A good convergence is observed almost until MH ≈ 2Mt. PACS numbers: 12.38.Bx 14.80.Bn
