为扭线器琴弦增添风味
Adding flavour to twistor strings
摘要:
扭转弦论被认为可以在树的层次上描述各种各样的场论,并且在微扰规范理论的实质性进展中被证明是非常有用的。通过在超扭量空间上的拓扑B模型中加入“味”膜,探讨了一类具有基本味的N=2 UV有限超杨-米尔斯理论的扭量对偶描述,并对这些对象的出现进行了评论.对应的证据是通过匹配两侧的振幅来提供的。
英文摘要:
Twistor string theory is known to describe a wide variety of field theories at tree-level and has proved extremely useful in making substantial progress in perturbative gauge theory. We explore the twistor dual description of a class of N=2 UV-finite super-Yang-Mills theories with fundamental flavour by adding 'flavour' branes to the topological B-model on super-twistor space and comment on the appearance of these objects. Evidence for the correspondence is provided by matching amplitudes on both sides.
