Discrimination of the light CP-odd scalars in the NMSSM and in the simplest little Higgs model

The presence of the light CP-odd scalar boson arising in the next-to-minimal supersymmetric model and the simplest little Higgs model dramatically changes the phenomenology of the Higgs sector. We suggest a practical strategy to discriminate the CP-odd scalar bosons between the two underlying models, produced in decays of the standard-model-like Higgs boson. We define the decay rate of "the non b-tagged jet pair," with which we compute the ratio of decay rates into leptons and jets. The ratio shows quite different behavior in the next-to-minimal supersymmetric model and the simplest little Higgs model.
