Soft Gluon Effects in Perturbative Quantum Chromodynamics*
The problem of the inclusion of sub-leading logarithms to all orders of the perturbative expansion is considered and solved in the case of multiple soft gluon emission. The evaluation of the entire set of the _ sub-dominant contributions is performed in a consistent way at two loop level in the impact parameter space for the effective quark form factor. The effect of the inclusion of the single...
متن کاملQuantum Chromodynamics: the Gluon Propagator Corresponding to Linear Confinement
The exact nonperturbative confining solutions of the SU(3)-Yang-Mills equations recently obtained by author in Minkowski spacetime with the help of the black hole theory techniques are analysed and on the basis of them the gluon propagator corresponding to linear confinement at large distances (small momenta) is constructed in a nonperturbative way. At small distances (large momenta) the result...
متن کاملGluon Jets from Heavy Paraquarkonium*
The GGG and qiG jets in the decay of very,heavy paraquarkonia are analyzed in perturbative quantum chromodynamics. The thrust distributions are calculated and the result is compared with the thrust distributions in the orthoquarkonium decay and in e'e-+ qqG jets. (Submitted to Physical Review D) * Work supported in part by the Department of Energy under contract DE-AC03-76SF00515, and in part b...
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.
