As a research team head: Exploration of the building blocks of the universe requires a detailed understanding of the scattering amplitudes in quantum field theories. The research in this field spans many directions — Infrared structure of scattering amplitudes, Celestial Amplitudes, Soft theorems, Resummation, Feynman integrals, etc.

In our latest work on Cwebs in multiparton scattering amplitudes we have introduce several new concepts: (a) Normal ordering of the diagrams of a Cweb, (b) Fused-Webs (c) Basis and Family of Cwebs. We use these ideas together with a Uniqueness theorem that we prove to arrive at an understanding of the the mixing matrices. See the section Research below for details.
