Hadronic Final State Predictions from Ccfm Generators

We have obtained a good description of F₂ and also the forward jet measurements at HERA as well as measurements on charm and bottom. Furthermore, with the same un-integrated gluon density, we obtained from a CCFM fit to F2, we are able to nicely describe also bbar b production at the TEVATRON. Some results are, however, very sensitive to effects of non-leading terms in the gluon splitting function, and more studies are needed before reliable predictions can be made with CCFM.
