Abstract

A brief review of the available experimental and theoretical results on the production of the $\chi_{Q1}$ states in $e^+e^-$ annihilation and photon-photon $\gamma\gamma^*$ interactions is presented. Future data on the production of the $\chi_{c1}(1P)$, $\chi_{c1}(3872)$, $\chi_{c1} (4140)$, $\chi_{c1}(4274)$, $\chi_{c1}(4685)$, $\chi_{b1} (1P)$, $\chi_{b1}(2P )$, and $\chi_{b1}(3P)$ resonances in $e^+e^-$ annihilation and $\gamma\gamma^*$ interactions will help the development and unification of theoretical predictions related to the electroweak decays of heavy quarkonia, the reduction of their spread and model uncertainties.
