The review of the transverse momentum dependent (TMD) gluon density and its application to analysis of pp and AA collisions in the wide region of initial energies at mid-rapidity is presented. It is shown that the non-colliniar QCD evolution is sensitive to the TMD gluon distributions at initial scale. The new TMD gluon density in a proton at is suggested using its saturation at low scales observed in DIS at HERA. Corresponding phenomenological parameters important at low are found from the best description of charged hadron spectra in collisions at low hadron transverse momenta in the mid-rapidity at the LHC energies. Other parameters important at moderate and large are found from the satisfactory description of many data on hard processes at LHC energies. The Catani-Ciafaloni-Fiorani-Marchesini (CCFM) evolution equation is applied to extend the initial gluon distribution into the whole kinematical region.
