Sažetak
The formalism for treating the leading-twist contributions of the two-gluon Fock components occurring in hard exclusive processes that involve η and η ′ mesons is reviewed. The calculation of the η, η ′–photon transition form factor in next-toleading order in αs, as well as, the analysis of the g ∗ g ∗η ′ vertex and the electroand photoproduction of η, η ′ mesons are presented. Applications of this formalism to other relevant quantities such as glueballs are also discussed.
