Heavy quark photoproduction in the k/sub [momento transverso]/-factorization approach

Abstract

We investigate heavy quark photoproduction based on the k'-factorization approach, focusing on the results from the saturation model. The deviations between the results using the unintegrated gluon distribution considering the saturation model and the derivative of the collinear gluon distribution are analyzed. Total cross sections and pT distributions are analyzed in detail, giving the deviations between the results of the color dipole approximation and the complete semihard approach.
