Abstract
The properties and behaviour of the solutions of the recently obtained kt -dependent QCD evolution equations are investigated. When used to reproduce transverse momentum spectra of hadrons in Semi-Inclusive DIS, an encouraging agreement with data is found. The present analysis also supports at the phenomenological level the factorization properties of the Semi-Inclusive DIS cross-sections in terms of kt -dependent distributions. Further improvements and possible developments of the proposed evolution equations are envisaged.| File | Dimensione | Formato | |
