Associated Charmonium-Bottomonium Production in a Single Boson <i>e</i>⁺<i>e</i>⁻ Annihilation

Abstract

The production cross sections of J/ψηb, Yηc pairs in a single boson e+e− annihilation have been studied in a wide range of energies, which will be achieved at future e+e− colliders. The main color singlet contributions to the production processes are taken into account, including the one loop QCD contribution.
