Here, the charge-conjugate $\\bar{p}J/\\psi$ is included. We observe clear $pJ/\\psi$ production in $\\Upsilon(1,2S)$ decays and measure the branching fractions to be $B[\\Upsilon(1S) \\to pJ/\\psi + anything] = [8.1 \\pm 0.6(stat.) \\pm 0.5(syst.)] \\times 10^{-5}$ and $B[\\Upsilon(2S) \\to pJ/\\psi + anything] = [4.3 \\pm 0.5(stat.) \\pm 0.4(syst.)] \\times 10^{-5}$.
