New Directions in Quantum Chromodynamics∗
I review the light-cone Fock state represention and its associated light-cone factorization scheme as a method for encoding the flavor, momentum, and helicity properties of hadrons in the form of universal process-independent and frame-independent amplitudes. Discrete light-cone quantization (DLCQ) provides a matrix representation of the QCD Hamiltonian and a nonperturbative method for computin...
متن کاملNew Perspectives in Quantum Chromodynamics*
In these lectures I will discuss three central topics in quantum chromodynamics: (1) the use of light cone quantization and Fock space methods to determ ine the long and -short-distance structure of quark and gluon distributions within hadrons; (2) th e role of spin, heavy quarks, and nuclei in unraveling fundamental phenomenological features of QCD; and (3) a new approach to understanding the ...
متن کاملQuantum Chromodynamics
After a brief historical review of the emergence of QCD as the quantum field theory of strong interactions, the basic notions of colour and gauge invariance are introduced leading to the QCD Lagrangian. The second lecture is devoted to perturbative QCD, from tree-level processes to higher-order corrections in renormalized perturbation theory, including jet production in e + e − annihilation , h...
متن کاملQuantum Chromodynamics *
The classical Lagrangian of chromodynamics, its quantization in the perturbation theory framework, and renormalization form the subject of these lectures. Symmetries of the theory are discussed. The dependence of the coupling constant αs on the renormalization scale μ is considered in detail.
متن کاملQuantum ChromoDynamics
These lectures on QCD stress the theoretical elements that underlie a wide range of phenomenological studies, particularly gauge invariance, renormalization, factorization and infrared safety. The three parts cover the basics of QCD, QCD at tree level and higher order corrections. Lectures given at the 2004 European School of High-Energy Physics, St. Feliu de Guı́xols, Barcelona, Spain, 30 May –...
