摘　　要：Vector meson photo-and electro-production on nucleon at high energies are important reactions to study the gluon component within nucleon.One of the main concerns of the planned Electron-Ion Collider in China(EicC)is near-threshold Upsilon(Υ(1S))production,where another two topics are critically relevant.First,it is an ideal machine to search for exotic nucleon states with hidden bottom(Pb),whose lowest mass in many theoretical models is expected to be a bit higher than Upsilon production threshold.Second,it is a promising platform to measure directly trace anomaly term in the proton mass decomposition,resulting into a deep exploration of the origin of the nucleon mass.
