The light meson decays of $D$ wave charmonia

Xiao-Yu Qi, Xing-Dao Guo, Dian-Yong Chen

Motivated by the large non- $D D ˉ$ branching fraction of $ψ (3770)$ , we investigate the light meson decays of the $D$ -wave charmonia in the present work with the meson loop mecha…

Two-body Hidden Charm Decays of $D$ Wave Charmonia

Xiao-Yu Qi, Qi Wu, Xing-Dao Guo +1

The experimental observations of $ψ_{2} (3823)$ and $ψ_{3} (3842)$ make $D$ wave charmonia family abundant. In the present work, we investigate the hidden charm decay processes of spin t…

Pionic transitions from $Z_{c} (4020)$ to $D$ wave charmonia

Xiao-Yu Qi, Qi Wu, Dian-Yong Chen

In the present work, we investigate the charmed meson loops contributions to the pionic transitions from $Z_{c} (4020)^{+}$ to the $D$ wave triplets charmonia by using an effective Lagr…
