Heavy Quark Photoproduction in kT Factorization Approach
Abstract
We investigate the heavy quark photoproduction based on the kT factorization approach, focusing on the results from the saturation model. The deviations in the results using the unintegrated gluon distribution considering the saturation model and the derivative of the collinear gluon distribution are analysed. Total cross sections and pT distributions are analysed in detail, setting the deviations between the color dipole approximation and the complete semihard approach.
