D=5 SU(2)xU(1)从D=11超重力测量的超重力

D=5 SU(2)xU(1) Gauged Supergravity from D=11 Supergravity

Jerome P. Gauntlett, Oscar Varela

摘要:

本文考虑D=11超引力场的最一般的超对称解,它由AdS_5与一个六维内流形N_6的翘曲积组成,它与d=4的N=2超共形场论是对偶的.对于任意一个这样的N_6,我们构造了完全非线性Kaluza-Klein近似,将N_6上D=11的超引力约化为D=5的SU(2)xU(1)规范超引力。这使得我们可以对任意给定的N_6,将D=5的超引力解提升到D=11的超引力解。利用一个显式的N_6,对应于在Calabi-Yau二重中包裹全纯曲线的M5-膜,我们提升了一些解,并评论了它们的解释。

英文摘要:

We consider the most general class of supersymmetric solutions of D=11 supergravity consisting of a warped product of AdS_5 with a six-dimensional internal manifold N_6, which are dual to N=2 super conformal field theories in d=4. For any such N_6 we construct the full non-linear Kaluza-Klein ansatz for the reduction of D=11 supergravity on N_6 down to D=5 SU(2)xU(1) gauged supergravity, at the level of the bosonic fields. This allows one to uplift any solution of the D=5 supergravity to obtain a solution of D=11 supergravity for any given N_6. Using an explicit N_6, corresponding to M5-branes wrapping holomorphic curves in a Calabi-Yau two-fold, we uplift some solutions and comment upon their interpretation.
