Neutral Higgs production at proton colliders in the CP-conserving NMSSM
arXiv:1502.07972 · doi:10.1140/epjc/s10052-015-3432-7
Abstract
We discuss neutral Higgs boson production through gluon fusion and bottom-quark annihilation in the CP-conserving -invariant Next-to-Minimal Supersymmetric Standard Model (NMSSM) at proton colliders. For gluon fusion we adapt known asymptotic expansions in supersymmetric particles for the inclusion of next-to-leading order contributions of squarks and gluinos from the Minimal Supersymmetric Standard Model (MSSM) and include electro-weak corrections involving light quarks. Together with the resummation of higher order sbottom contributions in the bottom-quark Yukawa coupling for both production processes we thus present accurate cross section predictions implemented in a new release of the code SusHi. We elaborate on the new features of an additional SU singlet in the production of CP-even and -odd Higgs bosons with respect to the MSSM and include a short discussion of theory uncertainties.
