AI总结:

本文研究连接不同环面Calabi-Yau 4-fold对应二维(0,2)规范理论的质量形变,结合brane brick模型分析几何变化、对称性破缺及Sasaki-Einstein体积与RG自由度的关系。

摘要:

我们研究了一类质量形变,它们连接了与不同环面Calabi-Yau 4-fold相关联的成对二维(0,2)规范理论。这些形变是著名的Klebanov-Witten形变在二维情形的推广;后者将C^2/Z_2 × C轨形与conifold对应的四维规范理论联系起来。我们考察了这些形变的多个方面,包括它们与brane brick模型的联系,以及几何变化与由形变触发的对称性破缺模式之间的关系。我们还探究了位于Calabi-Yau 4-fold基底的Sasaki-Einstein 7流形体积如何随形变变化,并由此猜想该体积可量化规范理论的自由度数及其对RG标度的依赖。

英文摘要:

We investigate a class of mass deformations that connect pairs of 2d (0,2) gauge theories associated to different toric Calabi-Yau 4-folds. These deformations are generalizations to 2d of the well-known Klebanov-Witten deformation relating the 4d gauge theories for the C^2/Z_2 x C orbifold and the conifold. We investigate various aspects of these deformations, including their connection to brane brick models and the relation between the change in the geometry and the pattern of symmetry breaking triggered by the deformation. We also explore how the volume of the Sasaki-Einstein 7-manifold at the base of the Calabi-Yau 4-fold varies under deformation, which leads us to conjecture that it quantifies the number of degrees of freedom of the gauge theory and its dependence on the RG scale.
