无取向D-膜瞬子的动力学超对称破缺

Dynamical supersymmetry breaking from unoriented D-brane instantons

Massimo Bianchi, Francesco Fucito, Jose F. Morales

摘要:

本文研究了具有规范群U(5)和手征物质的无取向Z_5-GUT类理论的非微扰动力学。在强耦合下,非微扰动力学用满足量子形变约束的重子/介子变量集来描述。我们计算了该理论的有效超势,并证明了它存在一条超对称真空线和一个超对称性通过高吉诺凝聚动态破缺的相。

英文摘要:

We study the non-perturbative dynamics of an unoriented Z_5-quiver theory of GUT kind with gauge group U(5) and chiral matter. At strong coupling the non-perturbative dynamics is described in terms of set of baryon/meson variables satisfying a quantum deformed constraint. We compute the effective superpotential of the theory and show that it admits a line of supersymmetric vacua and a phase where supersymmetry is dynamically broken via gaugino condensation.
