关于$W_4$ CFT中的几个三点函数及相关编织矩阵

On some 3-point functions in the $W_4$ CFT and related braiding matrix

P. Furlan, V. B. Petkova

摘要:

我们在$sl(4)$ Toda共形理论$W_4$中构造了一类三点常数,推广了Fateev和Litvinov中的例子.他们的知识允许确定的编织/融合矩阵变换4点共形块的一个基本的,标记的6维$sl(4)$表示,和三个部分退化的顶点算子。它是通用$6 \times 6$融合矩阵的$3 \times 3$子矩阵,与特定类别的表示的融合规则一致。我们检查的编织关系,具有更广泛的应用,共形模型与$sl(4)$对称性。在$\hat{sl}(4)$ WZW模型中,比较了中心荷双区域中的3点常数,为类似BPS的关系做准备。

英文摘要:

We construct a class of 3-point constants in the $sl(4)$ Toda conformal theory $W_4$, extending the examples in Fateev and Litvinov. Their knowledge allows to determine the braiding/fusing matrix transforming 4-point conformal blocks of one fundamental, labelled by the 6-dimensional $sl(4)$ representation, and three partially degenerate vertex operators. It is a $3 \times 3$ submatrix of the generic $6 \times 6$ fusing matrix consistent with the fusion rules for the particular class of representations. We check a braiding relation which has wider applications to conformal models with $sl(4)$ symmetry. The 3-point constants in dual regions of central charge are compared in preparation for a BPS like relation in the $\hat{sl}(4)$ WZW model.
