Measurement of double charmonium production in e(+)e(-) annihilations at root s=10.6 GeV

We study e+e-→J/ψcc̄ by measuring the invariant mass distribution recoiling against fully reconstructed J/ψ decays, using 124fb-1 of data collected at a center-of-mass energy of 10.6 GeV with the BABAR detector. We observe signals for ηc(1S), χc0, and ηc(2S) in the recoil mass distribution, thus con...
