复曲面几何的c-极值化

c-extremization from toric geometry

Antonio Amariti, Luca Cassia, Silvia Penati

摘要:

从常曲率黎曼曲面上拓扑扭曲的四维$\mathcal{N}=1$超共形场论的无限族中导出了二维中心荷$c_r$的几何公式。它们对应于复曲面规范规范理论,并与在AdS/CFT对应中探测五维Sasaki-Einstein几何的D3膜有关。我们表明,$c_r$可以表示在复曲面图描述的模空间的4D理论,无论是光滑和奇异的视野复曲面几何的领域。我们还研究了4d中的α-极大化与2d中的c-极值化之间的关系,进一步证明了重子对称性与二维精确R流的混合。

英文摘要:

We derive a geometric formulation of the 2d central charge $c_r$ from infinite families of 4d $\mathcal{N}=1$ superconformal field theories topologically twisted on constant curvature Riemann surfaces. They correspond to toric quiver gauge theories and are associated to D3 branes probing five dimensional Sasaki-Einstein geometries in the AdS/CFT correspondence. We show that $c_r$ can be expressed in terms of the areas of the toric diagram describing the moduli space of the 4d theory, both for toric geometries with smooth and singular horizons. We also study the relation between a-maximization in 4d and c-extremization in 2d, giving further evidences of the mixing of the baryonic symmetries with the exact R-current in two dimensions.
