Local integrands for two-loop QCD amplitudes

TL;DR

This paper reviews recent progress in computing two-loop five- and six-gluon amplitudes in Yang-Mills theory using local integrands that clarify infrared pole structures and explore connections with BCJ relations and all-multiplicity patterns.

Contribution

It introduces local integrands for two-loop amplitudes that explicitly reveal infrared structures and discusses their relation to BCJ relations and all-multiplicity frameworks.

Findings

Local integrands make infrared poles manifest.

Connection between integrands and BCJ relations explored.

Insights into all-multiplicity amplitude structures.

Abstract

In this talk we review the recent computation of the five- and six-gluon two-loop amplitudes in Yang-Mills theory using local integrands which make the infrared pole structure manifest. We make some remarks on the connection with BCJ relations and the all-multiplicity structure.
