Can we discover a light singlet-like NMSSM Higgs boson at the LHC? — •Conny Beskidt¹, Wim de Boer¹, and Dmitri Kazakov^1,2 — ¹Karlsruhe Institute of Technology (IETP) — ²JINR, ITEP, Moscow, Russia

In the next-to minimal supersymmetric standard model (NMSSM) one expects an additional singlet-like Higgs boson with small couplings to standard model (SM) particles via mixing. Although the mass can be well below the discovered 125 GeV Higgs boson its small couplings may make it difficult to discover it at the LHC. We use a novel scanning technique to efficiently scan the whole parameter space and determine the range of cross sections and branching ratios. This allows to give perspectives for the future searches for light Higgs bosons at the LHC with luminosities up to 300 and 3000 1/fb. Specific LHC benchmark points are selected, which represent the salient NMSSM features.
