  The heavy quark production in ultraperipheral heavy ion collisions is
investigated, in particular we focus on the results from the coherent
interactions given by the two-photon process. One addresses the heavy quark
total cross sections at photon level considering the saturation model and the
BFKL dynamics in the color dipole picture. The corresponding cross sections at
nuclear level are presented. It is verified that the QCD dynamics implies an
enhancement of the cross section in comparison with previous calculations.
