$^7 / \mathbf{Z}_k$中的1/2- BPS膜瞬子

1/2-BPS membrane instantons in AdS$_4 \times$S$^7 / \mathbf{Z}_k$

Jaemo Park, Hyeonjoon Shin

摘要:

根据AdS $_4 \times \mathbf{CP}^3$背景下D-膜的协变开超弦描述,1/2-BPS D 2-膜是纯瞬调的。在此基础上,采用11维的观点,我们识别了AdS $_4 \times$ S $^7 / \mathbf{Z}_k$背景中的1/2-BPS瞬变M2膜组态,在大$k$极限下,该组态约化为AdS $_4 \times \mathbf{CP}^3$,并计算了它们的作用值.我们还考虑了以前已知的1/2-BPS瞬变天体在十维M2膜的观点,以比较我们的结果。

英文摘要:

According to the covariant open superstring description of D-branes in the AdS$_4 \times \mathbf{CP}^3$ background, 1/2-BPS D2-branes are purely instantonic. Based on this and by taking the eleven dimensional viewpoint, we identify the 1/2-BPS instantonic M2-brane configurations in the AdS$_4 \times$ S$^7 / \mathbf{Z}_k$ background, which reduces to the AdS$_4 \times \mathbf{CP}^3$ under the large $k$ limit, and evaluate their action values. We also consider the previously known 1/2-BPS instantonic objects in ten dimensions from the M2-brane viewpoint to compare with our results.
