Manuscript Title: APFEL: A PDF Evolution Library with QED corrections | ||

Authors: Valerio Bertone, Stefano Carrazza, Juan Rojo | ||

Program title: APFEL | ||

Catalogue identifier: AESQ_v1_0Distribution format: tar.gz | ||

Journal reference: Comput. Phys. Commun. 185(2014)1647 | ||

Programming language: Fortran 77, C/C++ and Python. | ||

Computer: All. | ||

Operating system: All. | ||

RAM: ≤ 2MB | ||

Keywords: Unpolarised parton distribution functions (PDFs), DGLAP evolution equations, QED corrections, Electroweak effects, Deep-inelastic scattering (DIS). | ||

Classification: 11.6. | ||

External routines: LHAPDF | ||

Nature of problem:Solution of the unpolarized coupled DGLAP evolution equations up to NNLO in QCD and to LO in QED in the variable-flavor-number scheme, both with pole and with MSbar masses. | ||

Solution method:Representation of parton distributions and splitting functions on a grid in x, discretization of DGLAP evolution equations
and
higher-order interpolation for general values of x, numerical solution
of the
resulting discretized evolution equations using Runge-Kutta methods. | ||

Restrictions:Smoothness of the initial conditions for the PDF evolution. | ||

Running time:A few seconds for initialisation, then ~0.5 s for the generation of the PDF tables with combined QCD⊗QED evolution (on a Intel(R) Core(TM)2 Duo CPU E6750 @ 2.66GHz). |
