Conformality and Gauge Coupling Unification
It has been recently proposed to embed the standard model in a conformal gauge theory to resolve the hierarchy problem, and to avoid assuming either grand unification or low-energy supersymmetry. By model building based on string-field duality we show how to maintain the successful prediction of an electroweak mixing angle with sinθ ≃ 0.231 in conformal gauge theories with three chiral families.
متن کاملConformality and Brodsky
In this article I describe the recently-conjectured field-string duality which suggests a class of nonsupersymmetric gauge theories which are conformal (CGT) to leading order of 1/N and some of which may be conformal for finite N. If the standard model becomes conformal at TeV scales, modelbuilding on this basis is an interesting direction. Some remarks are added about the inspiring career of S...
متن کامل“Self-tuning” and Conformality
We consider an infinite-volume brane world setup where a codimension one brane is coupled to bulk gravity plus a scalar field with vanishing potential. The latter is protected by bulk supersymmetry, which is intact even if brane supersymmetry is completely broken as the volume of the extra dimension is infinite. Within this setup we discuss a flat solution with a “self-tuning” property, that is...
متن کاملOn some criterion of conformality
In the paper it is shown that in order to prove the conformality of a given diffeomorphism between Riemannian manifolds it is enough to limit investigation to the conformal modules of some special families of curves. The main result (Theorem 1.1) asserts that a sufficient condition for the conformality of a diffeomorphism is the conservation of n-modules of a family of mutually orthogonal 1-dim...
متن کاملDark Matter Candidate from Conformality
Abelian quiver gauge theories provide candidates for the conformality approach to physics beyond the standard model which possess novel cancellation mechanisms for quadratic divergences. A Z2 symmetry (R parity) can be imposed and leads naturally to a dark matter candidate which is the Lightest Conformality Particle (LCP), a neutral spin-1/2 state with weak interaction annihilation cross sectio...
