Probing Pion Valence Quark Distribution with Beam-charge Asymmetry of Pion-induced $J / ψ$ Production

Wen-Chen Chang, Marco Meyer-Conde, Jen-Chieh Peng +2

We consider the beam-charge asymmetry of the $J / ψ$ production cross sections in $π^{-}$ - versus $π^{+}$ -induced reactions on proton or nuclear targets. We show that the $J / ψ$ productio…

Constraining kaon PDFs from Drell-Yan and $J / ψ$ production

Wen-Chen Chang, Jen-Chieh Peng, Stephane Platchkov +1

The kaon parton distribution functions (PDFs) are poorly known due to paucity of kaon-induced Drell-Yan data. Nevertheless, these Drell-Yan data suggest a softer valence $u$ quark…
