Minimal Nonminimal Supersymmetric Standard Model

Original · EN

We review the basic field-theoretic and phenomenological features of the recently introduced Minimal Nonminimal Supersymmetric Standard Model (MNSSM). The introduced model is the simplest and most economic version among the proposed nonminimal supersymmetric models, in which the so-called μ-problem can be successfully addressed. As opposed to the MSSM and the frequently-discussed NMSSM, the MNSSM can naturally predict the existence of a light charged Higgs boson with a mass smaller than 100 GeV. Such a possible realization of the Higgs sector can be soon be tested at the upgraded Run II phase of the Tevatron collider.
