Description
Inspired by the 750 GeV resonance displayed in Run II by the ATLAS and CMS experiments, we propose to incorporate it in an extension of the MSSM based on a suitable gauge symmetry G. The combination of G and a U(1) R-symmetry yields a unique renormalizable superpotential containing a G-singlet superfield S, such that G breaks to MSSM at scale M with supersymmetry unbroken. The mass of the predicted MSSM singlet scalar resonance, as well as masses of the associated MSSM vectorlike fields do not exceed the symmetry breaking scale M because of G and U(1)_R, and indeed can be considerably smaller. The MSSM mu problem is elegantly resolved in these models. We present details for two models including production cross sections and decay widths based on well known U(1) extensions of the MSSM.
