We study the role of the non-perturbative input to the transverse momentum dependent (TMD) gluon density in hard processes at the LHC. We derive the TMD gluon distribution from the fit of the inclusive hadron spectra measured at low transverse momenta in [Formula: see text] collisions at the LHC and demonstrate that the best description of these spectra for larger hadron transverse momenta can be achieved by matching the derived TMD gluon distribution with the exact solution of the Balitsky-Fadin-Kuraev-Lipatov (BFKL) equation obtained at small transverse momenta outside the saturation region. A special attention is put to the phenomenological applications of presented TMD parton densities to some LHC processes, which are sensitive to the quark and gluon content of a proton.

I discuss double-diffractive (double-elastic) production of the η′ and ηc mesons in the pp → pXp reaction within the formalism of unintegrated gluon distribution functions (UGDF). The contribution of γ*γ* → η′ fusion is estimated. The distributions in the Feynman xF (or rapidity), transferred four-momenta squared between initial and final protons (t1, t2) and azimuthal angle difference between outgoing protons (Φ) are calculated and discussed. The results are compared with the WA102 data. Predictions at higher energies are presented.
