Charmonium content of $\ddot{I}{‡}_{c1}(3872)$ in light-cone sum rules at twist 3

Tarik Akan, Mehmet Ali Olpak, Altug Ozpineci

In this study, we utilize light-cone QCD sum rules at twist-3 accuracy to compute the coupling parameters of the $\ddot{I}{‡}_{c1}(2P)$ state with $D$ and $D^{\ast }$ mesons. The analysis reveals…
