Selected Topics in Theoretical High-Energy Physics: Scattering Amplitudes

This course will focus on scattering amplitudes which are central objects in quantum field theory used to confront theory with experiment. Topics covered include: foundations of scattering theory, classification of particles, relativistic kinematics, spinor-helicity formalism, unitarity and causality constraints, on-shell recursion relations, effective field theories, infrared and ultraviolet divergences, theory of complex angular momenta, emergence of classical physics, gravitational S-matrix.
