摘要：
We examine the fixed point behavior of Yukawa couplings in supersymmetric theories with varying numbers of dimensions. We show that Pendleton-Ross fixed point behavior is greatly amplified in the MSSM with no extra dimensions and 4 extra 5 + (5) over bar multiplets or the MSSM with one extra large dimension and 3 extra 5 + (5) over bar multiplets. We also show that power law running in models with large extra dimensions can give a hierarchical set of quasi-fixed points for the Yukawa couplings in a manner which is similar to the Froggatt-Nielsen mechanism. However, we also point out the limited perturbative domain in models with power law running. [S0556-2821(99)02405-4].
