At small x, the effects of finite transverse momenta of partons inside a hadron become increasingly important, especially in analyses of jets and heavy-quark production. These effects can be systematically accounted for in a formalism based on k_\perp -factorization and unintegrated distribution functions. We present results for the integrated and unintegrated distribution functions obtained within the framework of the Linked Dipole Chain model. Comparisons are made to results obtained within other approaches.
