We examine scenarios in the Next-to-Minimal Supersymmetric Standard Model (NMSSM) whereby two Standard Model-like Higgs bosons are produced via squark and gluino decay cascades along with two light, low-momentum neutrino Lightest Supersymmetric Particles (LSPs), resulting in very little Missing Transverse Energy (MET). Firstly, by recasting a general-purpose Jets+MET αT-based analysis we demonstrate how the sensitivity of current SUSY search efforts decreases in certain regions of parameter space within these scenarios. Finally we develop a novel search technique utilising machine learning-driven double-b-tagging variables for the case where each Higgs boson decays to a boosted bb pair.
