Associated charmonium-bottomonium production in a single boson $e^+e^-$ annihilation

TL;DR

This paper investigates the production cross sections of specific charmonium-bottomonium pairs in electron-positron annihilation, considering color singlet contributions and one-loop QCD effects, relevant for future collider energies.

Contribution

It provides a detailed calculation of production cross sections for charmonium-bottomonium pairs, including one-loop QCD corrections, in a context applicable to upcoming $e^+e^-$ collider experiments.

Findings

Calculated cross sections for $J/\psi~\eta_b$ and $\Upsilon\;\eta_c$ production.

Included one-loop QCD contributions to the production processes.

Results are relevant for experimental studies at future $e^+e^-$ colliders.

Abstract

The production cross sections of $J/\psi~\eta_b$, $\Upsilon\;\eta_c$ 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.
