Gluon distribution in proton at soft and hard pp collisions

We analyze the inclusive spectra of hadrons produced in pp collisions at high energies in the mid-rapidity region within the soft QCD and perturbative QCD assuming the possible creation of the soft gluons at low intrinsic transverse momenta k T . From the best description of the LHC data we found the parametrization of the unintegrated gluon distribution at low k T .
