Abstract

We found the parameterization of the unintegrated gluon distribution from the best description of the LHC data on the inclusive spectra of hadrons produced in pp collisions at the mid-rapidity region and small transverse momenta. It is different from the one obtained within perturbative QCD only at low intrinsic transverse momenta k_t. The application of this distribution to analysis of the e-p DIS allows us to get the results which do not contradict the H1 and ZEUS data on the structure functions at low x. So, the connection between the soft processes at LHC and low-x physics at HERA is found.
