Mass corrections of vector meson distribution amplitudes
G. Stoll
A model-independent way of computing the mass corrections of vector-meson distribution amplitudes is given. The method is based on resummation of (next-to-)leading twist local oper…

Light-cone wave functions of the photon: classification up to twist four
G. Stoll
The different light-cone wave functions of the photon up to twist four are defined. Some explicit expressions are extracted from results of Balitskii and al., Ali and Braun.

Light-cone wave functions of mesons
G. Stoll
A review of light-cone, covariant and gauge-invariant wave-functions of mesons is presented. They are basic non-perturbative objects needed for hard exclusive processes and for the…
