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. \u003c\/p\u003e\u003cp\u003eThis text is suitable for graduate students and non-specialist researchers alike as it requires only basic knowledge of perturbative QCD.\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eTable of Contents\u003c\/b\u003e\u003cbr\u003eIntroduction.- The Strategy of Regions.- Scalar SCET.- Generalization to QCD.- Resummation by RG Evolution.- Threshold Resummation in Drell-Yan Production.- Transverse Momentum Resummation.- IR Divergences of Gauge Theory Amplitudes.- Outlook.- One-Loop Integrals.- Inverse Derivative Operator.- Momentum-space Freynman Rules for Soft Wilson Lines.- Wilson Lines and Gauge Transformations.- Decoupling Transformation and the Gluon Kinetic Term.- Color Space Formalism.- Anomalous Dimensions.","brand":"Springer International Publishing AG","offers":[{"title":"Default Title","offer_id":52195428958551,"sku":"9783319148472","price":999.99,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0817\/1739\/5799\/files\/9783319148472.jpg?v=1763647576","url":"https:\/\/bookcurl.com\/products\/introduction-to-soft-collinear-effective-theory-9783319148472","provider":"Book Curl","version":"1.0","type":"link"}
