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…

Soft quark effects on H+jet production at NLP accuracy
Sourav Pal, Satyajit Seth
We define soft quark operators that enable construction of colour-ordered helicity amplitudes out of the non-radiative ones. We explore these operators for Higgs plus one jet produ…
