Non-Minimal and Non-Universal Supersymmetry
The discovery of D-branes allows gravity live in extra dimensions not felt by the gauge forces, and permits the effective gravitational coupling GNE 2 to be unified with the other gauge couplings at MGUT ∼ 10 GeV [2]. It also opens a Pandora’s box of many other higher-dimensional scenarios for the unification of gravity and gauge interactions, possibly at scales as low as 1 TeV [3]. However in ...
متن کاملNon-minimal Split Supersymmetry
We present an extension of the minimal split supersymmetry model, which is capable of explaining the baryon asymmetry of the Universe. Instead of MSSM we start from NMSSM and split its spectrum in such a way that the low energy theory contains neutral particles, in addition to the content of minimal split supersymmetry. They trigger the strongly first order electroweak phase transition (EWPT) a...
متن کامل′ from supersymmetry with non universal A terms ?
In supersymmetric theories with a motivated flavour structure we investigate the possibility that an ǫ ′ parameter as large as the measured value be generated without conflicting with the bounds from electron and neutron electric dipoles and µ → eγ.
متن کاملbetween 3 - form and non - minimal multiplet in supersymmetry
In analogy to the chiral-linear multiplet correspondence we establish a relationship between the 3-form (or gaugino condensate) multiplet and a coupled non-minimal (0, 1/2) multiplet, illustrated by a simple explicit example.
متن کاملǫ ′ from supersymmetry with non universal A terms ?
RGE effects characteristic of realistic unified theories lead to real non universal A terms that, together with complex Yukawa couplings, can produce a large contribution to ǫ ′ , as well as electron and neutron EDMs and µ → eγ decay. It does not seem impossible, with an appropriate sparticle spectrum, that an ǫ ′ as large as the measured value can be generated without conflicting with the boun...
