Among resummation techniques for perturbative QCD in the context of
collider and flavor physics, soft-collinear effective theory (SCET)
has emerged as both a powerful and versatile tool, having been
applied to a large variety of processes, from B-meson decays to jet
production at the LHC. This book provides a concise, pedagogical
introduction to this technique. 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.
