论文摘要
我们计算了$ O（n）$ sculetar理论到五环的$ o（n）$ o（n）$ c $ $ q $ qu $ qu $ quak $ q $的完整$ q $依赖性。重新归一化因子是从$ ϕ^q \ rightarrow q ϕ $ form formal中提取的，并且借助单位性切割方法构建了形式因素的积分。异常的尺寸与\ cite {badel：2019oxl，antipin：2020abu}中的已知结果相匹配，其中使用半经典方法获得了大$ q $限制中的前导和旋字母术语。
We compute the complete $Q$-dependence of anomalous dimensions of traceless symmetric tensor operator $ϕ^Q$ in $O(N)$ scalar theory to five-loop. The renormalization factors are extracted from $ϕ^Q\rightarrow Qϕ$ form factors, and the integrand of form factors are constructed with the help of unitarity cut method. The anomalous dimensions match the known results in \cite{Badel:2019oxl, Antipin:2020abu}, where the leading and subleading terms in the large $Q$ limit were obtained using a semiclassical method.
