Benchmark planes for Higgs-to-Higgs decays in the NMSSM

We present benchmark planes (or lines) with cross sections via gluon fusion for the processes H -> h + H-S, resonant Higgs pair and triple Higgs production, A -> h + (A(S) -> gamma gamma), A -> Z + h and A -> Z + H-S within the Next-to-Minimal Supersymmetric Standard Model. Moreover we propose new searches for H -> h + (H-S -> t (t) over bar), A -> Z + (H-S -> h+h) and A -> Z+ (H-S -> t (t) over bar) for which possible cross sections are given. These allow the experimental collaborations to verify in the future which search channels cover yet unexplored regions of the parameter space. Expressions for the dominant contributions to trilinear Higgs couplings and Higgs-Z couplings are discussed which allow to identify the dominant processes contributing to a given final state.

Automated summary

This study presents benchmark planes (or lines) with cross sections via gluon fusion within the Next-to-Minimal Supersymmetric Standard Model, for processes such as Higgs pair and triple Higgs production. New searches and possible cross sections for specific final states are proposed, aiming to explore unexplored regions of the parameter space. The dominant contributions to trilinear Higgs couplings and Higgs-Z couplings are discussed, aiding in the identification of the primary processes contributing to a given final state.
