  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.
