Description

Vector-meson exchange can be naturally introduced for both quark and hadron interactions in the framework of the hidden local symmetry (HLS) for the chiral dynamics. In the studies of Pc hadronic molecules [1,2] and whole spectrum of hadronic ground states [3,4], the vector meson exchanges are found to play more important role to reproduce the data than pseudoscalar meson exchanges, with many predictions to be checked by future experiments [4-6].
