Abstract
The next-to-minimal, supersymmetric Standard Model (nMSSM) predicts the existence of a light pseudo-scalar boson "a". If this particle were light enough, the decay of the Higgs boson into a pair of such particles. This scheme is searched for in several final states sensitive to different decay modes and mass ranges of the hypothetical pseudo-scalar, using ATLAS data amounting to either 20.3 fb−1 of p-p collisions at √s=8 TeV or between 3.2 fb−1 and 36.1 fb−1 at √s=13 TeV.
