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.
