NRQCD analysis of charmonium production with pion and proton beams at fixed-target energies

Chia-Yu Hsieh, Yu-Shiang Lian, Wen-Chen Chang +3

We present an analysis of hadroproduction of $J/\psi$ and $\psi (2S)$ at fixed-target energies in the framework of non-relativistic QCD (NRQCD). Using both pion- and proton-induced data,…
