摘要:

我们提出了SU(3)_C* SU(4)_W* U(1)_{B-L}模型的超对称SU(7)统一。这种统一方案在五维轨道中具有丰富的对称破缺链。本文详细研究了在Randall-Sundrum背景下,由边界条件引起的SUSY SU(7)对称破缺为SU(3)_C* SU(4)_W* U(1)_{B-L}及其AdS/CFT解释。我们发现,成功的规范耦合统一可以在我们的情况下实现。规范统一有利于低左右和统一尺度与树级\sin^2 θ_W=0.15。我们使用AdS/CFT对偶的共形超对称破缺的情况下,打破剩余的N=1的超对称。我们利用AdS/CFT方法再现了NSVZ公式,得到了强耦合区域(3/2N_c<N_F<3N_C)的Seiberg对偶的结构.我们表明,超对称性确实打破了共形超对称性破缺的情况下,消失的单重真空期望值。

英文摘要:

We propose the SUSY SU(7) unification of the SU(3)_C* SU(4)_W* U(1)_{B-L} model. Such unification scenario has rich symmetry breaking chains in a five-dimensional orbifold. We study in detail the SUSY SU(7) symmetry breaking into SU(3)_C* SU(4)_W* U(1)_{B-L} by boundary conditions in a Randall-Sundrum background and its AdS/CFT interpretation. We find that successful gauge coupling unification can be achieved in our scenario. Gauge unification favors low left-right and unification scales with tree-level \sin^2θ_W=0.15. We use the AdS/CFT dual of the conformal supersymmetry breaking scenario to break the remaining N=1 supersymmetry. We employ AdS/CFT to reproduce the NSVZ formula and obtain the structure of the Seiberg duality in the strong coupling region for 3/2N_c<N_F<3N_C. We show that supersymmetry is indeed broken in the conformal supersymmetry breaking scenario with a vanishing singlet vacuum expectation value.
