Partial Supersymmetry Breaking from Five Dimensions

Theories of partial supersymmetry breaking N = 2 → N = 1 in four dimensions are derived by coupling the N = 2 massless gravitino multiplet to N = 2 supergravity in five dimensions and performing a generalized dimensional reduction on S/Z2 with the Scherk-Schwarz mechanism. These theories agree with results that were previously derived from four dimensions.

Democratic Seesaw Mass Matrix Model

A seesaw mass matrix model is reviewed as a unification model of quark and lepton mass matrices. The model can understand why topquark mass mt is so singularly enhanced compared with other quark masses, especially, why mt ≫ mb in contrast to mu ∼ md, and why only top-quark mass is of the order of the electroweak scale ΛW , i.e., mt ∼ O(ΛW ). The model predicts the fourth up-quark t′ with a mass...

Theories in Five Dimensions

BPS and non-BPS orbits for extremal black-holes in N = 2 MaxwellEinstein supergravity theories (MESGT) in five dimensions were classified long ago by the present authors for the case of symmetric scalar manifolds. Motivated by these results and some recent work on non-supersymmetric attractors we show that attractor equations in N=2 MESGTs in d = 5 do indeed possess the distinct families of sol...
