Non-Perturbative Constraints on Light Sparticles from Properties of the RG Flow
摘要：
本文研究了在紫外和红外波段超共形场论场之间的一类强耦合四维R-对称重整化群流的超对称破缺微扰.我们分析的条件下，这些微扰规模为零，在深IR的领导秩序，导致意外的超对称性。此外，我们连接出现的IR超对称在这种情况下，最近被证实是更大的紫外线的基础超对称流的起点比在相应的IR端点的数量，我们提出了一个约束的紧急超对称。一路上，我们证明了一个简单而有用的非微扰定理的IR行为的全球风味电流。我们的研究结果表明，光阻粒子可以出现并可能影响大型强子对撞机的物理学的一般方式。
英文摘要：
We study certain small supersymmetry-breaking perturbations of a large class of strongly coupled four-dimensional R-symmetric renormalization group (RG) flows between superconformal field theories in the ultraviolet (UV) and the infrared (IR). We analyze the conditions under which these perturbations scale to zero at leading order in the deep IR, resulting in accidental supersymmetry. Furthermore, we connect the emergence of IR supersymmetry in this context with a quantity that was recently conjectured to be larger at the UV starting points of the underlying supersymmetric flows than at the corresponding IR endpoints, and we propose a bound on emergent supersymmetry. Along the way, we prove a simple and useful non-perturbative theorem regarding the IR behavior of global flavor currents. Our results suggest general ways in which light stop particles can emerge and potentially influence physics at the Large Hadron Collider.
