具有特殊超对称性的AdS $_3$解

AdS$_3$ solutions with exceptional supersymmetry

Giuseppe Dibitetto, Gabriele Lo Monaco, Achilleas Passias, Nicolò Petri, Alessandro Tomasiello

摘要:

在包含AdS $_3$等距的可能超代数中,两个有趣的可能性是例外的$F(4)$和$G(3)$。它们的R对称性分别为SO(7)和$G_2$,超对称性分别为${\cal N}=8$和${\cal N}=7$ .我们发现在IIA型超引力中存在两个实现这些超代数的(局部)唯一解,并给出了它们的解析表达式。在这两种情况下,内部空间都是由一个在一个间隔上包围的圆形六球获得的,一端是O 8平面。R对称是球的对称群;在$G(3)$的情况下,它被通量破缺为$G_2$。我们还发现了几个数值${\cal N}=1$解决方案与$G_2$味对称性,与各种本地化的来源,包括O2-平面和O 8-平面。

英文摘要:

Among the possible superalgebras that contain the AdS$_3$ isometries, two interesting possibilities are the exceptional $F(4)$ and $G(3)$. Their R-symmetry is respectively SO(7) and $G_2$, and the amount of supersymmetry ${\cal N}=8$ and ${\cal N}=7$. We find that there exist two (locally) unique solutions in type IIA supergravity that realize these superalgebras, and we provide their analytic expressions. In both cases, the internal space is obtained by a round six-sphere fibred over an interval, with an O8-plane at one end. The R-symmetry is the symmetry group of the sphere; in the $G(3)$ case, it is broken to $G_2$ by fluxes. We also find several numerical ${\cal N}=1$ solutions with $G_2$ flavor symmetry, with various localized sources, including O2-planes and O8-planes.
