摘要:

研究了正交辛代数OSp(6)的规范化问题|4)xSO(2)及其“对偶”OSp(2| 4)x SO(6),两者都基于具有相同例外陪集SO*(12)/U(6)的超引力和规范群SO(6)xSO(2)。这两个对偶理论是通过对规范N= 8AdS_4超引力作两种不同的截断得到的。我们明确研究的规范部门的两个对偶理论与超对称性所允许的最一般的群体。在无规范(super-Poincaré)的情况下,它们表现出相同的(大)黑洞吸引子解,具有1/N-BPS和非BPS配置之间的对偶关系。N=6的重力多重态还具有特殊性质,是OSp(6)的{ \em零中心模|4),因为它是基于SU(2,2)的四维超共形杨-米尔斯理论的情况下,|n)(PSU(2,2| 4)对于n=4)或OSp(n| 4)。

英文摘要:

We study the gauging of the orthosymplectic algebras OSp(6|4)xSO(2) and its "dual" OSp(2|4)x SO(6), both based on supergravities with the same exceptional coset SO*(12)/U(6), and gauge group SO(6)xSO(2). The two dual theories are obtained by two different truncations of gauged N=8 AdS_4 supergravity. We explicitly study the gauge sector of the two dual theories with the most general group allowed by supersymmetry. In the ungauged (super-Poincaré) case they exhibit the same (large) black-hole attractor solutions with dual relations between the 1/N-BPS and non-BPS configurations. The N=6 gravity multiplet has also the exceptional property to be a {\em zero-center module} of OSp(6|4), as it is the case for superconformal Yang--Mills theory in four dimensions based on SU(2,2|n) (PSU(2,2|4) for n=4) or OSp(n|4).
