Analysis of molecular state ${\eta }_c{D}^{\ast }$ and $J/\psi D^{\ast }$ in the effective Lagrangian approach

Na Li, Ye Xing, Jing-Rui Shi

In this work, we investigate the production and decay of the molecular states $cc\bar{c}\bar{q}$ with $J^P=1^{+}$ using the phenomenological analysis and effective Lagrangian approach.…
