Abstract

In the framework of the semihard (kT factorization) QCD approach, we consider the photoproduction of D* mesons associated with two hadron jets and the D* production in DIS at THERA conditions with the emphasis on the BFKL and CCFM dynamics of gluon distributions. In the photoproduction of D* mesons the attention is focused on the variable xγ, which is the fraction of the photon momentum contributed to a pair of jets with largest pT. We show that our theoretical results are sensitive to the BFKL type dynamics which may be investigated at THERA energies. We also discuss possible effect of /ψ meson spin alignement, which is thought to be a vivid manifestation of gluon off-shellness.
