| Publication Abstract: | High-accuracy ?-meson photoproduction data from EIC and EicC experiments will allow the measurement of the near-threshold total cross section of the reaction ?p ? ?p, from which the absolute value of the ?p-scattering length, j??pj, can be extracted using a vector-meson dominance model. For this evaluation, we used ?-meson photoproduction quasidata from the QCD approach (the production amplitude can be factorized in terms of gluonic generalized parton distributions and the quarkonium distribution amplitude). A comparative analysis of j??pj with the recently determined scattering lengths for ?p, ?p, and J=?p using the A2, CLAS, and GlueX experimental data are performed. The role of the young vector?meson effect is evaluated. |
