QCD Evolution Equations: Numerical Algorithms from the Laguerre Expansion
A complete numerical implementation, in both singlet and non-singlet sectors, of a very elegant method to solve the QCD Evolution equations, due to Furmanski and Petronzio, is presented. The algorithm is directly implemented in x-space by a Laguerre expansion of the parton distributions. All the leading-twist distributions are evolved: longitudinally polarized, transversely polarized and unpola...
متن کاملNumerical solution of DGLAP equations using Laguerre polynomials expansion and Monte Carlo method
We investigate the numerical solutions of the DGLAP evolution equations at the LO and NLO approximations, using the Laguerre polynomials expansion. The theoretical framework is based on Furmanski et al.'s articles. What makes the content of this paper different from other works, is that all calculations in the whole stages to extract the evolved parton distributions, are done numerically. The e...
متن کاملQCD evolution equations
We discuss QCD evolution equations for two and three particle correlation functions of quarks and gluon fields in a hadron which describe development of the momentum distribution of a parton system with a change of the wave length of a probe which resolves it. We show in a general case of two-particle correlators how the four-dimensional conformal algebra and the known pattern of conformal symm...
متن کاملevolution equations in QCD † Anna
The following lectures are an introduction to the phenomena of partonic saturation and nonlinear evolution equations in Quantum Chromodynamics. After a short introduction to the linear evolution, the problems of unitarity bound and parton saturation are discussed. The nonlinear Balitsky-Kovchegov evolution equation in the high energy limit is introduced, and the progress towards the understandi...
متن کاملEvolution Equations for High Parton Density Qcd
This talk is a brief report on our results in high parton density QCD. The main goal of this talk is to discuss the new evolution equation which was obtained and solved in Refs. [1] [2] and to share with you the physics can be recovered by this equation.
