Abstract

The discovery of a SM-like Higgs boson near 125 GeV and the flavor texture of the Standard Model motivate the investigation of supersymmetric quiver-like BSM extensions. We study the properties of such a minimal class of models which deals naturally with the SM parameters. Considering experimental bounds as well as constraints from flavor physics and Electro-Weak Precision Data, we find the following. In a self-contained minimal model — including the full dynamics of the Higgs sector — top squarks below a TeV are in tension with bsγ constraints. Relaxing the assumption concerning the mass generation of the heavy Higgses, we find that a stop not far from half a TeV is allowed. The models have some unique properties, e.g. an enhancement of the h\( b\overline{b} \) , \( \tau \overline{\tau} \) decays relative to the h → γγ one, a gluino about 3 times heavier than the stop, an inverted hierarchy of about 3 ÷ 20 between the squarks of the first two generations and the stop, relatively light Higgsino neutralino or stau NLSP, as well as heavy Higgses and a W which may be within reach of the LHC.
