Heavy Quark production at the TEVATRON and HERA using k_t-factorization with CCFM evolution
The application of k_t-factorization supplemented with the CCFM small-x
evolution equation to heavy quark production at the TEVATRON and at HERA is
discussed. The bb_bar production cross sections at the TEVATRON can be
consistently described using the k_t-factorization formalism together with the
unintegrated gluon density obtained within the CCFM evolution approach from a
fit to HERA F_2 data. Special attention is drawn to the comparison with
measured visible cross sections, which are compared to the hadron level Monte
