Inhaltsangabe:
- Correlators of Wilson-line, which capture eikonal contributions, are known to exponentiate in non-abelian gauge theories, and their logarithms can be organised in terms of collections of Feynman diagrams called webs. In~\cite{Agarwal:2020nyc} the concept of correlator web (Cweb), which is a set of skeleton diagrams built with connected gluon correlators and provides a generalisation of webs was introduced. The part of next-to-eikonal contributions to the scattering amplitude which exponentiates is given in terms of next-to-eikonal Cwebs~\cite{Gardi:2010rn,Laenen:2008gt}. In the present article we study next-to-eikonal Cwebs at three loop order, the order at which non trivial Cweb mixing matrices appear for the first time. The methods developed in~\cite{Agarwal:2022wyk} to construct mixing matrices directly without use of replica trick are used in this article to obtain the mixing matrices for next-to-eikonal Cwebs after we establish a relationship between next-to-eikonal and eikonal Cwebs.
