Measurement of Double Charmonium Production in $e^{+}{e}^{-}$ Annihilations at $\sqrt{s}=10.6$ GeV

The BABAR Collaboration, B. Aubert

We study $e^{+}{e}^{-}\to J/\psi c\bar{c}$ by measuring the invariant mass distribution recoiling against fully reconstructed $J/\psi$ decays, using 124 fb${}^{-1}$ of data collected with a cente…
