| Title | Threshold Upsilon-meson photoproduction at the EIC and EicC | ||||
| 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, ja¿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 ja¿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. | ||||
