Description

We present a new determination of the un-integrated PDF using the combined HERA data. We obtain acceptable chi*2/ndf. We find that for a good description of HERA data the gluon splitting function including non-singular terms as well as kinematic constraints and NLO alphas are necessary. We determine for the first time a full set of uncertainty uPDFs which allow to study the uPDF uncertainty for processes at HERA and the LHC. We also show a comparison of predictions using the new uPDFs with measurements from HERA and the LHC.
