膜和瞬子以一定角度相交

Branes and instantons intersecting at angles

Mirjam Cvetič, Iñaki García-Etxebarria, Robert Richter

摘要:

我们详细研究了IIA型弦论中的D 6膜和欧氏D2-膜瞬子相交系统。我们发现,在没有orientifolds的系统不有助于低能量的超势,与预期的基础上有效场论参数。我们还评论了我们的结果的双重弦论图片的影响。

英文摘要:

We study in detail the system of D6 branes and euclidean D2-brane instantons intersecting at angles in type IIA string theory. We find that in the absence of orientifolds the system does not contribute to the low energy superpotential, in agreement with expectations based on effective field theory arguments. We also comment on the implications of our results for dual string theory pictures.
