Cross section for double charmonium production in electron-positron annihilation at energy $\sqrt{s}$= 10.6 GeV

Elias Mengesha, Shashank Bhatnagar

In this work we study the process $e^{+}+e^{-}⟶J/\Psi +{\eta }_c$ at energy $\sqrt{s}=10.6GeV$ observed recently at B-factories whose measurements were made by Babar and…
