晶格上的超对称性和超杨-米尔斯模拟的现状

Supersymmetry on the lattice and the status of the Super-Yang-Mills simulations

Georg Bergner

摘要:

超对称(SUSY)和超对称场论是数值格子模拟中一个有趣的话题。类似于手征对称性,在晶格上也没有局部实现(相互作用)超对称性。我简要回顾了超对称破缺的基本原因。解决这个问题的一个尝试是使用超对称性的金斯帕-威尔逊关系。然而,除了自由理论,这个关系到目前为止还没有找到一个解决方案。对于超对称杨-米尔斯(SYM)理论的裸胶子质量的微调是足以达到一个超对称的连续极限。这项工作的最后一部分包含一个简短的状态报告,最近SYM模拟。

英文摘要:

Supersymmetry (SUSY) and supersymmetric field theories are an interesting topic for numerical lattice simulations. Similar to the chiral symmetry there is also no local realization of (interacting) supersymmetry on the lattice. I briefly review the basic reasons for the breaking of supersymmetry. One attempt to solve the problem uses a Ginsparg-Wilson relation for supersymmetry. However, apart from the free theory, a solution of this relation has so far not been found. For supersymmetric Yang-Mills (SYM) theory a fine-tuning of the bare gluino mass is enough to arrive at a supersymmetric continuum limit. The last part of this work contains a short status report of recent SYM simulations.
