CWebGen -- A tool to study colour structure of scattering amplitudes in IR limit
Neelima Agarwal, Sourav Pal, Aditya Srivastav +1
Infrared singularities in perturbative Quantum Chromodynamics (QCD) are captured by the Soft function, which can be calculated efficiently using Feynman diagrams known as webs. The…
Colour structure of next-to-eikonal correlator webs at three loops
Abhinava Danish, Shubham Mishra, Sourav Pal +2
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 collecti…
Multiparton Cwebs at five loops
Shubham Mishra, Sourav Pal, Aditya Srivastav +1
Scattering amplitudes involving multiple partons are plagued with infrared singularities. The soft singularities of the amplitude are captured by the soft function which is defined…
Correlator webs of massive multiparton amplitudes at four loops: A study of boomerang webs
Neelima Agarwal, Sourav Pal, Aditya Srivastav +1
Logarithm of the soft function can be organized into sets of Feynman diagrams known as Cwebs. We introduced a new formalism in~\cite{Agarwal:2022wyk}, that allows to determine seve…
