Finite N AdS/CFT Correspondence for Abelian and Nonabelian Orbifolds, and Gauge Coupling Unification | Paul H. Frampton
; | Date: |
17 Nov 2000 | Journal: | J.Math.Phys. 42 (2001) 2915-2928 | Subject: | hep-th | Abstract: | Although the AdS/CFT correspondence is rigorous only for an infinite $N o infty$ stack of D3-branes, it can be fruitfully studied for finite $N$ as a source of gauge structures and choices for chiral fermions and complex scalars which solve the hierarchy problem by a conformal fixed point. We emphasize orbifolds $AdS_5 imes S^5/Gamma$ where the resulting GFT has ${cal N} = 0$ supersymmetry. The fact that the complex scalars are prescribed by the construction limits the possible spontaneous symmetry breaking. Both abelian and nonabelian $Gamma$ are illustrated by simple examples. An accurate $sin^2 heta$ in electroweak unification can be obtained, suggesting that this approach merits further study. | Source: | arXiv, hep-th/0011165 | Services: | Forum | Review | PDF | Favorites |
