Exponentially Small Couplings between Twisted Fields of Orbifold String Theories
We investigate the natural occurrence of exponentially small couplings in effective field theories deduced from higher dimensional models. We calculate the coupling between twisted fields of the Z3 Abelian orbifold compactification of the heterotic string. Due to the propagation of massive Kaluza-Klein modes between the fixed points of the orbifold, the massless twisted fields located at these ...
متن کاملTwisted Supersymmetric Gauge Theories and Orbifold Lattices
We examine the relation between twisted versions of the extended supersymmetric gauge theories and supersymmetric orbifold lattices. In particular, for the N = 4 SYM in d = 4, we show that the continuum limit of orbifold lattice reproduces the twist introduced by Marcus, and the examples at lower dimensions are usually Blau-Thompson type. The orbifold lattice point group symmetry is a subgroup ...
متن کاملExponentially Small Couplings and the Hierarchy Problem
We propose a stringy mechanism whereby a large hierarchy between symmetry breaking scales is generated. This mechanism is based upon the existence of a fifth dimension compactified on a segment. We focus on a simple supersymmetric model with one massless Higgs field in the 3 of SU(3) and another one in the 3̄ on each four dimensional end point of the fifth dimension. Along supersymmetric flat di...
متن کاملMinimal String Unification and Yukawa Couplings in Orbifold Models
We study the minimal supersymmetric standard model derived from ZN × ZM orbifold models. Moduli dependent threshold corrections of the gauge couplings are investigated to explain the measured values of the coupling constants. Also we study Yukawa couplings of the models. We find that the Z2 × Z ′ 6, Z2 × Z6, Z3 × Z6 and Z6 × Z6 orbifold models have the possibility to derive Yukawa couplings for...
متن کاملLarge N orbifold field theories on the twisted torus
We study the planar equivalence of orbifold field theories on a small three-torus with twisted boundary conditions, generalizing the analysis of hep-th/0507267. The nonsupersymmetric orbifold models exhibit different large N dynamics from their supersymmetric ”parent” counterparts. In particular, a moduli space of Abelian zero modes is lifted by an O(N2) potential in the ”daughter” theories. We...
