Abstract: (Springer)
We discuss neutral Higgs boson production through gluon fusion and bottom-quark annihilation in the CP-conserving Z3\mathbb {Z}_3 -invariant Next-to-Minimal Supersymmetric Standard Model at proton colliders. For gluon fusion we adapt well-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 electroweak 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 (2)L(2)_L singlet in the production of CP-even and -odd Higgs bosons with respect to the MSSM and include a short discussion of theoretical uncertainties.
