摘要：
The results of theoretical calculations within the semihard (kT-factorization) approach are compared with the latest data obtained in the ZEUS experiment at the HERA collider for the inelastic electroproduction of J/ψ mesons in the kinematical region specified by the inequalities 2 GeV2 < Q2 < 80 GeV2, 50 GeV < W < 250 GeV, 0.2 < z < 0.9, and −1.6 < yψlab < 1.3. The dependence of these theoretical results on the choice of parametrization among three widely used parametrizations of unintegrated gluon distributions is studied.
