Descripción
Soft collinear effective theory (SCET) is the effective field theory of QCD suitable to describe processes involving very energetic collinear particles. Its first applications were in B decays (e.g., B \rightarrow \pi K), but quite recently the framework has been applied to the study of jets and the description of parton showers. In this talk I will motivate why an effective field theory approach can be useful in this context, taking e^+e^- into hadrons as a paradigm. In particular, I will explain how the SCET matching and running is performed and report on work in progress to describe e^+e^- into hadrons up to NNLO.
