Anomaly -从更高维度的观点看调解和隔离
Anomaly-Mediation and Sequestering from a Higher-Dimensional viewpoint
摘要：
我们研究了一个具有边界局域可见扇区的五维超引力模型，该模型表现出反常介导的超对称破缺，在该模型中，螯合和半径稳定的中心要求是微扰实现的.这使得我们能够以一种更加综合和透明的方式来理解这些不同的机制，主要是从更高维度的角度来理解。局部超对称性，在存在可见扇区量子效应的情况下，是由五维超共形张量演算的形式主义所加强的。这种结构只会导致轻微的翘曲，这使得（有限的）边界到边界重力环的自然超光速破坏调解机制与异常调解共同占主导地位，从而解决了后者的快子slepton问题。我们做了非平凡的检查，这可能发生，而稳定场的危险回路仍然高度抑制。我们的讨论是考虑反常中介的其他推广或弦论实现的良好控制的起点。
英文摘要：
We study a five-dimensional supergravity model with boundary-localized visible sector exhibiting anomaly-mediated supersymmetry breaking, in which the central requirements of sequestering and radius stabilization are achieved perturbatively. This makes it possible to understand these various mechanisms in a more integrated and transparent fashion, mostly from the higher-dimensional viewpoint. Local supersymmetry, in the presence of visible sector quantum effects, is enforced by the formalism of the five-dimensional superconformal tensor calculus. The construction results in only mild warping, which allows a natural supersymmetry-breaking mediation mechanism of (finite) boundary-to-boundary gravity loops to co-dominate with anomaly-mediation, thereby solving the latter's tachyonic slepton problem. We make the non-trivial check that this can occur while dangerous loops of stabilizing fields remain highly suppressed. Our discussion is a well-controlled starting point for considering other generalizations of anomaly-mediation, or for string theory realizations.
