Symmetry Breaking in Supersymmetric E6 Models
We study the electroweak and U(1) ′ symmetry breaking patterns in models with the particle content of supersymmetric E6, including standard model singlets S and exotic quarks D, D̄. Motivated by free fermionic string models, we do not require E6-type relations between Yukawa couplings. In particular, we assume that baryon and lepton numbers are conserved, so that the exotic quarks can be light. ...

متن کاملElectroweak Breaking in Supersymmetric Models *
We discuss the mechanism for electroweak symmetry breaking in supersymmetric versions of the standard model. After briefly reviewing the possible sources of supersymmetry breaking, we show how the required pattern of symmetry breaking can automatically result from the structure of quantum corrections in the theory. We demonstrate that this radiative breaking mechanism works well for a heavy top...
متن کاملLepton flavor violation in a supersymmetric E6 type model
Lepton flavor violating processes are obtained from the mixings between the ordinary leptons and the exotic leptons in the E6 27 representation. The effects of these lepton mixings are, however, suppressed naturally because of the hierarchy of the charged lepton masses. In the supersymmetric model, significant effects of lepton flavor violation rather appear through the slepton mixings which ar...
متن کاملSoft-breaking correction to hard supersymmetric relations
Supersymmetric relations between dimensionless couplings receive finite correction at one-loop when supersymmetry is broken softly. We calculate the O(αs) correction to the squark decay width to a quark and an electroweak gaugino, which is found to be nonvanishing. Logarithmic correction appears when the gluino is heavy.
