Journal reference: Comput. Phys. Commun. 118(1999)236 | ||

Programming language: Fortran. | ||

Computer: Sun 19. | ||

Operating system: Unix. | ||

Keywords: Structure function, Polarized parton, Distribution, Q**2 evolution, Laguerre expansions, Numerical solution, Particle physics, Elementary, Qcd. | ||

Classification: 11.5. | ||

Nature of problem:The programs provided here solve the DGLAP evolution equations, with next-to-leading order alphas effects taken to account, for unpolarized, longitudinally polarized and transversely polarized parton distributions. | ||

Solution method:The method developed by Furmanski and Pertonzio is used. The kernel P(x) of the DGLAP integrodifferential equations and the evolution operators E(t,x) are expanded in Laguerre polynomials. | ||

Running time:About 5 seconds for the transverse polarization case and 20 minutes for the longitudinal polarization and for the unpolarized. |
