Abstract

We present the perturbative parts of the structure functions F2c and F L c for a gluon target having nonzero transverse momentum squared at order α s . The results of the double convolution (with respect to the Bjorken variable x and the transverse momentum) of the perturbative part and the unintegrated gluon densities are compared with HERA experimental data for F2c and F L at low x values and with predictions of other approaches. The contribution from F L c structure function ranges 10÷30% of that of F2c at the HERA kinematical range.
