摘要：
We study the heavy quark production processes with the transverse momentum dependent (unintegrated) gluon distribution function in a proton which is obtained recently using the Kimber-Martin-Ryskin prescription from the Bessel-inspired behavior of parton densities at small Bjorken x values. Our results agree with the latest HERA experimental data for reduced cross sections sigma(c (c) over bar)(red) (x, Q(2)) and sigma(b (b) over bar)(red)(x, Q(2)), and also for deep inelastic structure functions F-2(c)(x, Q(2)) and (b)(F)(2)(x, Q(2)) in a wide range of x and Q(2) values. Comparisons with the predictions based on the Ciafaloni-Catani-Fiorani-Marchesini evolution equation and with the results of conventional pQCD calculations performed at the first three orders of perturbative expansion are presented.
