Supergravity Unification
A review is given of the historical developments of 1982 that lead to the supergravity unified model (SUGRA) with gravity mediated breaking of supersymmetry. Further developments and applications of the model in the period 1982-85 are also discussed. The supergravity unified model and its minimal version (mSUGRA) are currently among the leading candidates for physics beyond the Standard Model. ...
متن کاملHierarchies and textures in supergravity unification.
It is proposed that supergravity unified models contain in addition to the hidden and the visible sectors, a third sector which contains exotic matter with couplings to the fields of both the visible and the hidden sectors. After spontaneous breaking of supersymmetry exotic matter becomes superheavy and its elimination leads to quark-lepton textures at the GUT scale with a hierarchy in powers o...
متن کاملEffects of gravitational smearing on predictions of supergravity grand unification.
Limits on gravitational smearing from the dominant dimension 5 operator(with strength characterised by cM/2MP lanck) are obtained using the LEP data in supersymmetric SU(5) grand unification.Effects of c on the quasi infrared fixed point solutions of mb/mτ unification are also analysed.It is found that c > 0 softens and c < 0 stiffens the fixed point constraint. The effect of c on the upper bou...
متن کاملProbing supergravity grand unification in the Brookhaven g-2 experiment.
A quantitative analysis of aμ ≡ 12(g− 2)μ within the framework of Supergravity Grand Unification and radiative breaking of the electro-weak symmetry is given. It is found that a μ is dominated by the chiral interference term from the light chargino exchange, and that this term carries a signature which correlates strongly with the sign of μ. Thus as a rule a μ > 0 for μ > 0 and a SUSY μ < 0 for...
متن کاملSingularity Resolution in Gauged Supergravity and Conifold Unification
We obtain a unified picture for the conifold singularity resolution. We propose that gauged supergravity, through a novel prescription for the twisting, provides an appropriate framework to smooth out singularities in the context of gravity duals of supersymmetric gauge theories.
