Description
We study the phenomenological consequences of the supersymmetric (SUSY) E7/SU(5)× U(1)3 non-linear sigma model, where the squarks and sleptons are Nambu Goldstone (NG) bosons. This SUSY coset space accommodates just three families of the quark and lepton chiral multiplets as (pseudo) NG multiplets, explaining the origin of the families. The model coupled to the supergravity predicts a chiral multiplet which has shift symmetry. The imaginary part can be identified as the QCD axion solving the strong CP problem. The gaugino masses have a typical mass pattern from the anomaly mediation and the SUSY breaking mediation due to the chiral multiplet if the dominant SUSY breaking field is charged under some symmetry. The model predicts the difference of the wino and bino masses within O(1)%, which can lead to thermal dark matter with bino-wino coannihilation. Moreover we find that the regions for the dark matter abundance, the consistent Higgs boson mass, and the unification regions within O(1)% precision of the bottom-tau Yukawa couplings and the gauge couplings coincides, i.e. a NLS miracle. The scenario can be tested in the LHC and future colliders.
