New online web-application for APFEL, visit APFEL Web!

APFEL is able to perform DGLAP evolution up to NNLO in QCD and to LO in QED, both with pole and MSbar masses. The coupled DGLAP QCD+QED evolution equations are solved in x-space by means of higher order interpolations and Runge-Kutta techniques, and allows to explore different options for the treatment of subleading terms.

APFEL GUI: a graphical user interface

APFEL provides the user with a graphical interface which performs PDF, luminosity and DIS observables plots in real time, granting an easy access to all the APFEL's functionalities.
