标量-向量自举

Scalar-Vector Bootstrap

Fernando Rejon-Barrera, Daniel Robbins

摘要:

我们工作的共形引导程序适用于四点函数的两个标量和两个向量在任意维的抽象共形场论的实施所需的所有细节。这包括审查张量结构的外观,建设所需的混合对称表示的投影仪,并计算所有可能的运营商可以交换的共形块。这些块作为微分算子作用于先前已知的标量共形块。最后,我们建立了实现交叉对称的自举方程。特别注意的情况下,保守的向量,发生几个简化。

英文摘要:

We work out all of the details required for implementation of the conformal bootstrap program applied to the four-point function of two scalars and two vectors in an abstract conformal field theory in arbitrary dimension. This includes a review of which tensor structures make appearances, a construction of the projectors onto the required mixed symmetry representations, and a computation of the conformal blocks for all possible operators which can be exchanged. These blocks are presented as differential operators acting upon the previously known scalar conformal blocks. Finally, we set up the bootstrap equations which implement crossing symmetry. Special attention is given to the case of conserved vectors, where several simplifications occur.
