特殊完整流形中的膜和通量与级联场论

Branes and fluxes in special holonomy manifolds and cascading field theories

Akikazu Hashimoto, Shinji Hirano, Peter Ouyang

摘要:

我们研究了全息RG流,其UV是与重力解耦的2+1维理论,IR是ABJM的N= 6,8超共形不动点。我们考虑的解是通过扭曲M理论背景构造的,其八个空间维度是特殊完整性sp(1)乘以sp(1)和自旋(7)的流形。我们的自旋(7)完整流形的主要例子是最初由Cvetic,Gibbons,Lu和Pope构造的A8几何。在引力方面,我们的构造推广了早期的RG流构造,其中UV是N=3的Yang-Mills-Chern-Simons物质系统,并且在许多方面更简单。通过仔细考虑佩奇,麦克斯韦和膜电荷,我们确定了离散和连续参数表征每个系统。然后,我们确定的范围内的离散数据,对应于通量/秩的超对称性是未破缺的,并估计作为这些数据的函数的动态超对称性破缺规模。然后,我们指出我们的系统和系统之间的超对称性破缺的物理学的相似性考虑Maldacena和Nastase。我们还描述了不破缺超对称性的条件,基于另一类称为B8空间的自旋(7)流形,其IR不同于ABJM,并表现出一些有趣的功能。

英文摘要:

We conduct a study of holographic RG flows whose UV is a theory in 2+1 dimensions decoupled from gravity, and the IR is the N=6,8 superconformal fixed point of ABJM. The solutions we consider are constructed by warping the M-theory background whose eight spatial dimensions are manifolds of special holonomies sp(1) times sp(1) and spin(7). Our main example for the spin(7) holonomy manifold is the A8 geometry originally constructed by Cvetic, Gibbons, Lu, and Pope. On the gravity side, our constructions generalize the earlier construction of RG flow where the UV was N=3 Yang-Mills-Chern-Simons matter system and are simpler in a number of ways. Through careful consideration of Page, Maxwell, and brane charges, we identify the discrete and continuous parameters characterizing each system. We then determine the range of the discrete data, corresponding to the flux/rank for which the supersymmetry is unbroken, and estimate the dynamical supersymmetry breaking scale as a function of these data. We then point out the similarity between the physics of supersymmetry breaking between our system and the system considered by Maldacena and Nastase. We also describe the condition for unbroken supersymmetry on class of construction based on a different class of spin(7) manifolds known as B8 spaces whose IR is different from that of ABJM and exhibit some interesting features.
