K3上M-理论中的BPS和非BPS 7维黑吸引子

BPS and non BPS 7D Black Attractors in M-Theory on K3

El Hassan Saidi

摘要:

研究了K3上紧化的11维M-理论中7维N=2超引力中的BPS和非BPS黑吸引子。结合Kahler和复模的SO(3)表示,我们建立了K3的二阶上同调的Dalbeault like(DL)基,并建立了7 D理论基础模空间的特殊“超Kahler”几何的基本关系.利用有效势临界性方法和四维新吸引子方法对7 DN =2超引力的推广,研究了7 D黑膜的吸引子方程.关于6D/7 D对应关系,沿着用于4D/5D的Ceresole-Ferrara-Marrani线(参考arXiv:0707.0964)进行评论。

英文摘要:

We study the BPS and non BPS black attractors in 7D N=2 supergravity embedded in 11D M-theory compactified on K3. Combining Kahler and complex moduli in terms of SO(3) representations, we build the Dalbeault like (DL) basis for the second cohomology of K3 and set up the fundamental relations of the special "hyperKahler" geometry of the underlying moduli space of the 7D theory. We study the attractor eqs of the 7D black branes by using the method of the criticality of the effective potential and also by using the extension of the so called 4D new attractor approach to 7D N=2 supergravity. A comment, regarding a 6D/7D correspondence, along the line of Ceresole-Ferrara-Marrani used for 4D/5D, ref.arXiv:0707.0964, is made.
