Towards precision determination of unintegrated Parton Density Functions

arXiv:hep-ph/0611093

Abstract

First attempts are described to determine the unintegrated Parton Density Function of the gluon from a fit to measurements of the structure function $F_{2} (x, Q^{2})$ and also $F_{2}^{c} (x, Q^{2})$ measured at HERA. Reasonable descriptions of both structure functions are obtained, but the gluon densities determined are different.
