Monte Carlo solution of the DGLAP evolution equation and extraction of TMD densities — •Aleksandra Lelek1, Hannes Jung1, and Francesco Hautmann2 — 1DESY, Hamburg, Germany — 2University of Oxford, Oxford, United Kingdom
The Sudakov form factor, with its simple physical interpretation as a probability of evolving from one scale to another without any resolvable branching, is a basic tool to solve the evolution equation with a Monte Carlo method.
We present results for the full quark and gluon parton densities obtained with uPDFevolv code. We demonstrate that this method gives an exact solution of the evolution equation by a comparison with the results from the QCDnum package. We also show that higher order splitting functions can be included in a straight forward manner. The MC methods provides a direct method to obtain transverse momentum dependent (TMD) parton densities.
