Abstract: (Elsevier)
The analytic solution of the evolution equations in QCD is given in the form of a series of Laguerre polynomials in the variable y = In ( 1 x ) . The Laguerre series converges very quickly and it can be truncated after few terms with a reasonable accuracy. Also high precision calculations are possible since the coefficients of the series are given by simple recurrence formulae. The method works both for non-singlet and for singlet spectra and it can be applied to any hard process. The inclusion of higher order effects is immediate. The Laguerre technique provides a natural framework for extracting from the data the input quark and gluon distributions without any prejudices concerning their particular analytic form.- LEPTON HADRON: DEEP INELASTIC SCATTERING
