    Muon g-2, 125 GeV Higgs boson, and neutralino dark matter in a flavor symmetry-based MSSM
    (Amer Physical, 2014-12-16) Babu, Kaladi S.; Gogoladze, Ilia G.; Shafi, Qaisar; Ün, Cem Salih; Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Fizik Bölümü.; 0000-0002-0595-8803; N-3421-2014; 55325758100
    We discuss the sparticle (and Higgs) spectrum in a class of flavor symmetry-based minimal super-symmetric standard models, referred to here as sMSSM. In this framework the supersymmetry breaking Lagrangian takes the most general form consistent with a grand unified symmetry such as SO(10) and a non-Abelian flavor symmetry acting on the three families with either a 2+1 or a 3 family assignment. Models based on gauged SU(2) and SO(3) flavor symmetry, as well as non-Abelian discrete symmetries such as S-3 and A(4), have been suggested which fall into this category. These models describe supersymmetry breaking in terms of seven phenomenological parameters. The soft supersymmetry breaking masses at M-GUT of all sfermions of the first two families are equal in sMSSM, which differ in general from the corresponding third family mass. In such a framework we show that the muon g - 2 anomaly, the observed Higgs boson mass of similar to 125 GeV, and the observed relic neutralino dark matter abundance can be simultaneously accommodated. The resolution of the muon g - 2 anomaly in particular yields the result that the first two generation squark masses, as well the gluino mass, should be less than or similar to 2 TeV, which will be tested at LHC14.
