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.
