At the fundamental level, the interactions of elementary particles are described by quantum gauge field theory. The quantitative implications of these interacti
Outlining a revolutionary reformulation of the foundations of perturbative quantum field theory, this book is a self-contained and authoritative analysis of the
This open access book bridges a gap between introductory Quantum Field Theory (QFT) courses and state-of-the-art research in scattering amplitudes. It covers th
