Comparison of SDME and Amplitude Methods in Description of Vector-Meson Production
It is argued that the amplitude method (direct extraction of helicity-amplitude ratios from data on vector-meson production with hard photon) has much advantages compared to the standard spin-density-matrix-element method for construction of generalized parton distributions from experimental data on nucleons.
