Universality at next-to-leading power for jet associated processes
Sourav Pal, Satyajit Seth
The study of cross-sections in the threshold limit at next-to-leading power has been a subject of sustained interest for many years. We demonstrate the universality of leading loga…

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…

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…
