The remaining parts for the long-standing J/psi polarization puzzle

Yu Feng, Bin Gong, Chao-Hsi Chang +1

Based on the non-relativistic quantum chromodynamics factorization formalism, the polarization parameters $λ_{θ ϕ}$ and $λ_{ϕ}$ of $J / ψ$ hadroproduction are analyzed in helicity frame…

Double longitudinal-spin asymmetries in $J / ψ$ production at RHIC

Yu Feng, Hong-Fei Zhang

The double longitudinal-spin asymmetry, $A_{LL}$ , of the $J / ψ$ production in polarized proton-proton collisions is presented in this paper at QCD next-to-leading order. It is found…
