Transition between soft physics at LHC and low-x physics at HERA

Abstract

We find out the connection between the unintegrated gluon distribution at low intrinsic transverse momenta and the inclusive spectrum of the hadrons produced in pp collision at LHC energies in the mid-rapidity region and low hadron transverse momenta. The parameters of this distribution are found from the best description of the LHC data. Its application to the analysis of ep deep inelastic scattering allows us to obtain the results which reasonable describe the H1 and ZEUS data on the structure functions at low x. The connection between the soft processes at LHC and small-x physics at HERA is found.
