${\chi }_{cJ}$ production in $e^{+}{e}^{-}$ annihilation

Abstract

Inclusive production of ${\chi }_{cJ}$ in $e^{+}{e}^{-}$ annihilation is an excellent probe of the role of higher Fock states in the production of heavy quarkonia. Within the non-relativistic QCD approach, contributions from the short-distance production of colour-octet $c\bar{c}$ pairs are significantly larger than those from colour-singlet production. At the same time, ${\chi }_{cJ}$ production rates are significantly smaller than expected in the colour evaporation approach. Measurements of ${\chi }_{\stackrel{¸}{J}}$ production at CLEO and future B-factories will thus constitute a major test of theoretical approaches to the production of heavy quarkonia.
