Measurement of $J/\ddot{I}ˆ$ and $\ddot{I}ˆ\left(2S\right)$ production in $p+p$ and $p+d$ interactions at 120 GeV

We report the $p+p$ and $p+d$ differential cross sections measured in the SeaQuest experiment for $J/\ddot{I}ˆ$ and $\ddot{I}ˆ\left(2S\right)$ production at 120 GeV beam energy covering the forw…
