Testing Quantum Chromodynamics*
The difficulties in isolating specific QCD mechanisms which control hadronic phenomena, and the complications in obtaining quantitative tests of QCD are discussed. A number of novel QCD effects are reviewed, including heavy quark and higher twist phenomena, initial and final state interactions, direct processesI multiparticle collisions, color filtering, and nuclear target effects. The importan...
متن کاملTesting Quantum Chromodynamics in Electroproductjon
Deep inelastic lepton nucleon scattering has been’one of the key testing grounds of QCD over the past two decades. Measurements of the nucleon and nuclear structure functions have not only tested the short-distance properties of the theory, (such as the scaling properties of structure functions and their logarithmic evolution with momentum transfer), but they have also illuminated the nonpertur...
متن کاملTesting Quantum Chromodynamics with Antiprotons
The antiproton storage ring HESR to be constructed at GSI will open up a new range of perturbative and nonperturbative tests of QCD in exclusive and inclusive reactions. I discuss 21 tests of QCD using antiproton beams which can illuminate novel features of QCD. The proposed experiments include the formation of exotic hadrons, measurements of timelike generalized parton distributions, the produ...
متن کاملTesting Quantum Chromodynamics in Anti-proton Reactions*
An experimental program with anti-protons at intermediate energy can serve as an important testing ground for QCD. Detailed predictions for exclusive cross sections at large momentum transfer based on perturbative QCD and the QCD sum rule form of the proton distribution amplitude are available for j?p + y-y -for both real and virtual photons. Meson-pair and lepton-pair final states also . . giv...
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...
