BRST invariant effective action of shadow fields, conformal fields, and AdS/CFT

R. R. Metsaev

摘要:

研究了AdS空间中的全对称任意自旋无质量场和有质量场.对于这样的领域,我们得到拉格朗日是不变的全球BRST变换。拉格朗日函数用于计算配分函数和有效作用量。我们证明了在规范无质量场和Faddeev-Popov场Dirichlet问题解上的无质量场的BRST不变体作用量导致了正则阴影规范场和阴影Faddeev-Popov场的BRST不变有效作用量,而大质量场的BRST不变体作用量则由规范大质量场的Dirichlet问题和Faddeev-Popov场导致反常阴影规范场和阴影Faddeev-Popov场的BRST不变有效作用量。正则阴影场的正则化有效作用量的领先对数发散导致共形场的简单BRST不变作用量。我们证明了进入共形场的BRST不变拉格朗日量的Nakanishi-Laudrup场可以几何地解释为无质量AdS场的边界值。

英文摘要:

Totally symmetric arbitrary spin massless and massive fields in AdS space are studied. For such fields, we obtain Lagrangians which are invariant under global BRST transformations. The Lagrangians are used for computation of partition functions and effective actions. We demonstrate that BRST invariant bulk action for massless field evaluated on the solution of Dirichlet problem for gauge massless fields and Faddeev-Popov fields leads to BRST invariant effective action for canonical shadow gauge fields and shadow Faddeev-Popov fields, while the BRST invariant bulk action for massive field evaluated on the solution of Dirichlet problem for gauge massive fields and Faddeev-Popov fields leads to BRST invariant effective action for anomalous shadow gauge fields and shadow Faddeev-Popov fields. The leading logarithmic divergence of the regularized effective action for the canonical shadow field leads to simple BRST invariant action of conformal field. We demonstrate that the Nakanishi-Laudrup fields entering the BRST invariant Lagrangian of conformal field can geometrically be interpreted as boundary values of massless AdS fields.
