The ρ-meson longitudinal leading-twist distribution amplitude

The ρ-meson longitudinal leading-twist distribution amplitude

In the present paper, we suggest a convenient model for the vector ρ-meson longitudinal leading-twist distribution amplitude ϕ2;ρ‖, whose distribution is controlled by a single parameter B2;ρ‖. By choosing proper chiral current in the correlator, we obtain new light-cone sum rules (LCSR) for the B→ρ...
