Type 1 2HDM as effective theory of supersymmetry
It is generally believed that the low energy effective theory of the minimal
supersymmetric standard model is the type 2 two Higgs doublet model. We will
show that the type 1 two Higgs doublet model can also as the effective of
supersymmetry in a specific case with high scale supersymmetry breaking and
gauge mediation. If the other electroweak doublet obtain the vacuum expectation
value after the electroweak symmetry breaking, the Higgs spectrum is quite
different. A remarkable feature is that the physical Higgs boson mass can 125
GeV unlike in the ordinary models with high scale supersymmetry in which the
Higgs mass is generally around 140 GeV.Comment: 11 pages, 3 figures, Published in Commun.Theor.Phy
Reconfigurable Optical Interconnections Via Dynamic Computer-Generated Holograms
A system is presented for optically providing one-to-many irregular interconnections, and strength-adjustable many-to-many irregular interconnections which may be provided with strengths (weights) w(sub ij) using multiple laser beams which address multiple holograms and means for combining the beams modified by the holograms to form multiple interconnections, such as a cross-bar switching network. The optical means for interconnection is based on entering a series of complex computer-generated holograms on an electrically addressed spatial light modulator for real-time reconfigurations, thus providing flexibility for interconnection networks for large-scale practical use. By employing multiple sources and holograms, the number of interconnection patterns achieved is increased greatly
