“…In particular, the effective NMSSM Higgs coupling to the gluons normalized to the corresponding coupling of a SM Higgs boson is obtained by taking the ratio of the partial width for the Higgs decay into gluons in the NMSSM and the SM, respectively. The program NMSSMCALC takes into account the QCD corrections up to next-to-next-to-next-to leading order in the limit of heavy quark [112][113][114][115][116][117][118][119][120][121] and squark [122,123] masses. They can be taken over from the SM, respectively, MSSM case.…”

Abstract:We provide the two-loop corrections to the Higgs boson masses of the CPviolating NMSSM in the Feynman diagrammatic approach with vanishing external momentum at O(α t α s ). The adopted renormalization scheme is a mixture between DR and on-shell conditions. Additionally, the renormalization of the top/stop sector is provided both for the DR and the on-shell scheme. The calculation is performed in the gaugeless limit. We find that the two-loop corrections compared to the one-loop corrections are of the order of 5-10%, depending on the top/stop renormalization scheme. The theoretical error on the Higgs boson masses is reduced due to the inclusion of these higher order corrections.

“…We have compared our result with the expression in [25], in the non-physical region. The result of [25] was derived by series expanding the integral representation of the two-loop amplitude from [3] in a kinematic variable, and mapping the expansion to a carefully chosen ansatz. Our result agrees with [25].…”

“…As discussed in the introduction, the fermionic contributions have been computed in [3] and expressed in terms of 8 one-dimensional integrals. In turn, these integrals were computed in terms of harmonic polylogarithms in [25], giving the analytical result for the two loop corrections with fermions in the loop.…”

Abstract:We compute all two-loop master integrals which are required for the evaluation of next-to-leading order QCD corrections in Higgs boson production via gluon fusion. Many two-loop amplitudes for 2 → 1 processes in the Standard Model and beyond can be expressed in terms of these integrals using automated reduction techniques. These integrals also form a subset of the master integrals for more complicated 2 → 2 amplitudes with massive propagators in the loops. As a first application, we evaluate the two-loop amplitude for Higgs boson production in gluon fusion via a massive quark. Our result is the first independent check of the calculation of Spira, Djouadi, Graudenz and Zerwas. We also present for the first time the two-loop amplitude for gg → h via a massive squark.

“…They are known both for infinite [24] and finite [25,26] loop quark masses and, at the √ s = 7 TeV LHC, lead to a K-factor K NLO ∼ 1.8 in the low Higgs mass range, if the central scale of the cross section is chosen to be M H . It has been shown in Ref.…”

Abstract. I review the theoretical aspects of the physics of Higgs bosons, focusing on the elements that are relevant for the production and detection at present hadron colliders. After briefly summarizing the basics of electroweak symmetry breaking in the Standard Model, I discuss Higgs production at the LHC and at the Tevatron, with some focus on the main production mechanism, the gluon-gluon fusion process, and summarize the main Higgs decay modes and the experimental detection channels. I then briefly survey the case of the minimal supersymmetric extension of the Standard Model. In a last section, I review the prospects for determining the fundamental properties of the Higgs particles once they have been experimentally observed.
