چکیده

We consider the Higgs boson production in the gluon-fusion channel to nextto-next-to-leading order within the Minimal Supersymmetric Standard Model. In particular, we present analytical results for the matching coefficient of the effective theory and study its influence on the total production cross section in the limit where the masses of all MSSM particles coincide. For supersymmetric masses below 500 GeV we observe a significant enhancement of the Standard Model cross section, the K factor, however, changes only marginally. PACS numbers: 12.38.Bx 14.80.Bn

SusHi 1.1.1: A program for the calculation of Higgs production in gluon fusion and bottom-quark annihilation in the Standard Model, the 2HDM and the MSSM

This article describes the code SusHi (for “Supersymmetric Higgs”) [1] which calculates the cross sections pp/pp → φ + X in gluon fusion and bottom-quark annihilation in the SM, the 2HDM and the MSSM, where φ is any of the neutral Higgs bosons within these models. Apart from inclusive cross sections up to NNLO QCD, differential cross sections with respect to the Higgs transverse momentum pT and...

Higgs production in hadron collisions: soft and virtual QCD corrections at NNLO

We consider QCD corrections to Higgs boson production through gluon–gluon fusion in hadron collisions. Using the recently evaluated [14]two-loop amplitude for this process and the corresponding factorization formulae [15, 16, 17, 18] describing soft-gluon bremsstrahlung at O(α2 S), we compute the soft and virtual contributions to the next-to-next-to-leading order cross section. We also discuss ...

MSSM Higgs Boson Production via Gluon Fusion: The Large Gluino Mass Limit

Scalar MSSM Higgs boson production via gluon fusion gg → h,H is mediated by heavy quark and squark loops. The higher order QCD corrections to these processes turn out to be large. The full supersymmetric QCD corrections have been calculated recently. In the limit of large SUSY masses a conceptual problem appears, i.e. the proper treatment of the large gluino mass limit. In this work we will des...
