Probing the fabric
of the universe

Exploration of the building blocks of the universe requires a detailed understanding of scattering amplitudes in quantum field theories. Our research, which specialises in perturbative Quantum Chromodynamics (QCD) spans many directions — infrared structure of scattering amplitudes, resummation, Feynman integrals, etc.

Latest Work — Cwebs in Multiparton Scattering: We have introduced several new concepts including normal ordering of Cweb diagrams, Fused-Webs, and a Basis and Family of Cwebs. Combined with a Uniqueness Theorem, these ideas give a complete understanding of the mixing matrices arising in the exponentiation of multi-parton scattering amplitudes.

New Directions — Quantum Computing: Our group has strong interest in the application of Quantum Computation to Quantum Field Theories and we are actively working in this direction.
