Analysis of molecular state η c D * and J / ψD * in the effective Lagrangian approach*
Abstract
Abstract In this work, we investigate the production and decay of molecular states with quark content and using a phenomenological analysis and an effective Lagrangian approach. Based on an SU (3) flavor-symmetry analysis to identify golden channels, we further explore the dynamics of these processes under the molecular assumptions of and . Our results indicate that the production branching ratio in decays is sizable: it can be of order for the molecular configuration and for the molecule . In addition, we find that the decay widths of the two molecular configurations and are not significant, at the level of ( ).
