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

Abstract

We present benchmark planes (or lines) with cross sections via gluon fusion for the processes Hrightarrow h+H_{S}, resonant Higgs pair and triple Higgs production, A rightarrow h+(A_S rightarrow gamma gamma ), A rightarrow Z+ h and A rightarrow Z+ H_{S} within the Next-to-Minimal Supersymmetric Standard Model. Moreover we propose new searches for Hrightarrow h+(H_{S} rightarrow t{bar{t}}), A rightarrow Z+ (H_{S}rightarrow h+h) and A rightarrow Z+ (H_{S}rightarrow t{bar{t}}) 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.
