Abstract

This course provides a pedagogical introduction to an advanced topic in Quantum Field Theories, which has undergone a tremendous progress in the new millennium: scattering amplitudes and on-shell methods.

Objective

Students that complete the course will be able to understand the basics of the modern methods to compute scattering amplitudes, to perform simple calculations and to read modern publications on this research field.

Content

This course covers the basic concepts of: -- spinor helicity formalism -- colour decompositions -- BCFW on-shell recursion relations -- BCJ colour-kinematics duality -- Feynman integrals: IBPs and differential equations -- analytic and algebraic structure of loop-level amplitudes: * Hopf algebras, symbols and coproducts * multiple polylogarithms (a.k.a. as iterated integrals on the Riemann sphere) * Steinmann relations * coaction principle * elliptic and modular-form integrals (a.k.a. as iterated integrals on the torus)
