${\chi }_{c1}$ and ${\chi }_{c2}$ production at $e^{+}{e}^{-}$ colliders

Abstract

Direct, resonant production of the charmonium states ${\chi }_{c1}$ and ${\chi }_{c2}$ in electron-positron annihilation is investigated. Depending on details of the model, a sizeable variation of the prediction for the production cross section is anticipated. It is demonstrated that resonant production could be observed under favorable circumstances.
