六维$(2,0)$理论中反常维数的递推关系

Recursion Relations for Anomalous Dimensions in the 6d $(2,0)$ Theory

Theresa Abl, Paul Heslop, Arthur E. Lipstein

摘要:

我们推导了6维$(2,0)$理论中四点应力张量展开子的共形块展开中出现的双迹算子的反常维数的递推关系,它编码了M理论产生的$AdS_7 \times S^4$中对超引力的高阶导数修正.作为热身,我们推导了玩具非超对称6维共形场论中标量算子的四点函数的类似递推关系。

英文摘要:

We derive recursion relations for the anomalous dimensions of double-trace operators occurring in the conformal block expansion of four-point stress tensor correlators in the 6d $(2,0)$ theory, which encode higher-derivative corrections to supergravity in $AdS_7 \times S^4$ arising from M-theory. As a warm-up, we derive analogous recursion relations for four-point functions of scalar operators in a toy non-supersymmetric 6d conformal field theory.
