It discusses the expansion of Feynman diagrams around the high-energy limit, followed by the explicit construction of the effective Lagrangian - first for a scalar theory, then for QCD. The underlying concepts are illustrated with the quark vector form factor at large momentum transfer, and the formalism is applied to compute soft-gluon resummation and to perform transverse-momentum resummation for the Drell-Yan process utilizing renormalization group evolution in SCET. Finally, the infrared structure of n-point gauge-theory amplitudes is analyzed by relating them to effective-theory operators. This text is suitable for graduate students and non-specialist researchers alike as it requires only basic knowledge of perturbative QCD.Lecture Notes in Physics,1616-6361 ;896Particles (Nuclear physics)Quantum field theoryElementary Particles, Quantum Field TheoryParticles (Nuclear physics)Quantum field theory.Elementary Particles, Quantum Field Theory.530.143Becher Thomasauthttp://id.loc.gov/vocabulary/relators/aut984129Broggio Alessandroauthttp://id.loc.gov/vocabulary/relators/autFerroglia Andreaauthttp://id.loc.gov/vocabulary/relators/autMiAaPQMiAaPQMiAaPQBOOK9910131336603321Introduction to Soft-Collinear Effective Theory2247671UNINA
