Using the measured e+e- -> gamma X(3872) cross section as a reference, the authors predict measurable e+e- -> gamma chi_c0(2P) and e+e- -> gamma chi_c2(2P) production and propose the gamma D Dbar final state as a search channel.

abstract
We study the observed $B^-\rightarrow X(3823)K^-$ decay via rescattering mechanism and show that this branching ratio is well reproduced by this mechanism. We further extend this theoretical framework to investigate the decays of $B^-\to\eta_{c2} (^1D_2)/\psi_3(^3D_3)K^-$, where the $\eta_{c2} (^1D_2)$ and the $\psi_3(^3D_3)$ are $D$-wave charmonium partners of the $X(3823)$. Our results show that the branching ratios, $B^-\to \eta_{c2}(^1D_2) K^-$ and $B^-\to \psi_3(^3D_3) K^-$, are of the order of $10^{-5}$, which can be accessible at LHCb, Belle and forthcoming BelleII.

Discovery potential of charmonium $2P$ states through the $e^+e^- \to \gamma D\bar{D}$ processes
