Polarization of prompt J/psi in pp -> J/psi+X at sqrt{s}=200 GeV
Hee Sok Chung, Seyong Kim, Jungil Lee +1
Within the framework of the nonrelativistic QCD factorization approach, we compute the cross section and polarization of prompt J/psi produced from proton-proton collisions at the…

NRQCD matrix elements for S-wave bottomonia and Gamma[eta_b(nS) -> gamma gamma] with relativistic corrections
Hee Sok Chung, Jungil Lee, Chaehyun Yu
We determine the leading-order nonrelativistic quantum chromodynamics (NRQCD) matrix element < O_1 >_Upsilon and the ratio < q^2>_Upsilon, for Upsilon=Upsilon(nS) with n=1, 2, and…
