Virtual corrections to Higgs boson pair production in the large top quark mass limit
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 ...
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
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 کاملMSSM Higgs boson in the large pseudoscalar - mass limit
We investigate the decoupling properties of the Higgs-sector-induced one-loop corrections in the lightest Higgs-boson self-couplings, in the framework of the Minimal Supersymmetric Standard Model. The renormalized n-point vertex functions with external Higgs particles in the MSSM and in the SM are derived to one-loop level and compared in the M A 0 ≫ M Z limit. The computation has been done in ...
متن کاملHiggs 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.
