AdS_3上高自旋场的Higgs现象

Higgs phenomenon for higher spin fields on AdS_3

Thomas Creutzig, Yasuaki Hikida

摘要:

研究了具有N=3超共形对称性的2d陪集模型的边缘形变,并将其解释为对偶高自旋理论中体场边界条件的改变.这种形变破坏了一般的高自旋规范对称性,并计算了自旋为2的场的生成质量。这种变形可能与超弦理论中有限弦张力的引入有关。在本文中,我们扩展了分析,并计算了一般的高自旋场的质量在1/c(c是CFT的中心荷)的领先顺序,但在全阶的变形参数。我们发现,在此量级上,SO(3)R单重态高自旋场不产生质量,SO(3)R三重态高自旋荷电场的谱是类Regge谱。

英文摘要:

In a previous work, a marginal deformation of 2d coset type model with N=3 superconformal symmetry was studied, and it was interpreted as a change of boundary conditions for bulk fields in the dual higher spin theory. The deformation breaks generic higher spin gauge symmetry, and the generated mass of a spin 2 field was computed. The deformation might be related to the introduction of finite string tension in a superstring theory. In this paper, we extend the analysis and compute the masses of generic higher spin fields at the leading order of 1/c (c is the CFT central charge) but at the full order of the deformation parameter. We find that the masses are not generated for so(3)_R singlet higher spin fields at this order and the spectrum is the Regge-like one for so(3)_R triplet higher spin-charged fields.
