Nonanomalous Discrete R-Symmetry and Light Gravitino
We discuss nonanomalous R-symmetry in the supersymmetric grand unified theories. In particular, we explore anomaly-free solutions predicting the gravitino mass in the range of 10 eV∼m3/2 ∼ 1 TeV when the μ-parameter is fixed to be μ ≃ 1 TeV. In the minimal SU(5) GUT, we have shown that μ ≃ 1 TeV is obtained only if the gravitino is ultralight with mass m3/2 ∼ 10 eV. If extra fields 5⊕ 5 or 10⊕ ...
متن کاملNonanomalous discrete R symmetry decrees three generations.
We show that more than two generations of quarks and leptons are required to have an anomaly free discrete R symmetry larger than R parity, provided that the supersymmetric standard model can be minimally embedded into a grand unified theory. This connects an explanation for the number of generations with seemingly unrelated problems such as supersymmetry breaking, proton decay, the μ problem, ...
متن کاملFlavor Symmetry and Quark Model of Hadrons
As discussed in the previous Chapter, when the universe cools below TC , quarks and gluons are clustered to form color-singlet hadrons. When the temperature gets sufficiently low, the anti-baryon density becomes negligible, and the excess baryon number (or baryon chemical potential) decides the density of residual baryons. Because the proton and neutrons (together called nucleons) are the lowes...
متن کاملCorrosion Protection of Steel Using Nonanomalous Ni-Zn-P Coatings
A novel technique for obtaining nonanomalous Ni-Zn-P coatings with high Ni content ~74 wt % as compared to 15-20 wt % in the conventional plating method! has been developed. These coatings show promise as a replacement for Cd in sacrificially protecting steel. Ni-Zn-P coatings were deposited using an electroless method from a solution containing NiSO4 , complexing agent and ammonium chloride. V...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
