超共形Chern-Simons理论与AdS_4/CFT_3对应

Superconformal Chern-Simons Theories and AdS_4/CFT_3 Correspondence

Marcus Benna, Igor Klebanov, Thomas Klose, Mikael Smedbäck

摘要:

讨论了N=8超共形Bagger-Lambert-Gustavsson理论和N=6超共形Aharony-Bergman-Jafferis-Maldacena U(N)xU(N)Chern-Simons理论的N=2超空间形式.特别地,我们证明了ABJM理论的完全SU(4)R-对称性。然后我们考虑这个理论的轨道投影,给出了非手征和手征的(U(N)xU(N))^n超共形规范规范理论。我们认为这些理论与M-理论的某些AdS_4 × S^7/(Z_n × Z_k)背景是对偶的。我们还研究了超势中的一个SU(3)不变质量项,它使N=8理论流到一个具有六次超势的N=2超共形规范理论.我们猜想这个规范理论与N.华纳25年前,其提升到11维是最近发现的。

英文摘要:

We discuss the N=2 superspace formulation of the N=8 superconformal Bagger-Lambert-Gustavsson theory, and of the N=6 superconformal Aharony-Bergman-Jafferis-Maldacena U(N)xU(N) Chern-Simons theory. In particular, we prove the full SU(4) R-symmetry of the ABJM theory. We then consider orbifold projections of this theory that give non-chiral and chiral (U(N)xU(N))^n superconformal quiver gauge theories. We argue that these theories are dual to certain AdS_4 x S^7/(Z_n x Z_k) backgrounds of M-theory. We also study a SU(3) invariant mass term in the superpotential that makes the N=8 theory flow to a N=2 superconformal gauge theory with a sextic superpotential. We conjecture that this gauge theory is dual to the U(1)_R x SU(3) invariant extremum of the N=8 gauged supergravity, which was discovered by N. Warner 25 years ago and whose uplifting to 11 dimensions was found more recently.
