Revisiting NLO QCD corrections to total inclusive J/psi and Upsilon photoproduction cross sections in lepton-proton collisions
Alice Colpani Serri, Yu Feng, Carlo Flore +4
We revisit inclusive J/psi and Upsilon photoproduction at lepton-hadron colliders, namely in the limit when the exchanged photon is quasi real. Our computation includes the next-to…
The complete study on polarization of hadroproduction at QCD next-to-leading order
Yu Feng, Bin Gong, Chao-Hsi Chang +1
Applying the nonrelativistic quantum chromodynamics factorization formalism to the hadroproduction, a complete analysis on the polarization parameters , …
Exclusive quarkonium production or decay in soft gluon factorization
Rong Li, Yu Feng, Yan-Qing Ma
In this paper, we study the application of the recently proposed soft gluon factorization (SGF) to exclusive quarkonium production or decay. We find that in the nonrelativistic QCD…
Kinematic distributions of the photoproduction in collisions within the nonrelativistic QCD framework
Hong-Fei Zhang, Yu Feng, Wen-Long Sang +1
We study the photoproduction in collisions in this paper. The short-distance coefficients for , , ,…
Phenomenological NLO analysis of eta(c) production at the LHC in the collider and fixed-target modes
Yu Feng, Jibo He, Jean-Philippe Lansberg +3
In view of the good agreement between the LHCb prompt-eta(c) data at sqrt(s)=7 and 8 TeV and the NLO colour-singlet model predictions --i.e. the leading v^2 NRQCD contribution--, w…
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 and of hadroproduction are analyzed in helicity frame…

Yu Feng, Hong-Fei Zhang
The double longitudinal-spin asymmetry, , of the production in polarized proton-proton collisions is presented in this paper at QCD next-to-leading order. It is found…
Is the colour-octet mechanism consistent with the double production measurement at B-factories?
Yu Feng, Zhan Sun, Hong-Fei Zhang
Double production in collisions involving colour-octet channels are evaluated up to order . Having implemented the variation of the parameters (, $μ_r…
Next-To-Leading Order Differential Cross-Sections for , and Production in Proton-Proton Collisions at a Fixed-Target Experiment using the LHC Beams (AFTER@LHC)
Y. Feng, J. -X. Wang
Using nonrelativistic QCD (NRQCD) factorization, we calculate the yields for , and hadroproduction at 72 GeV and 115 GeV including the next-to-lead…
Energy Dependence of Direct-Quarkonium Production in pp Collisions from Fixed-Target to LHC Energies: Complete One-Loop Analysis
Yu Feng, Jean-Philippe Lansberg, Jian-Xiong Wang
We compute the energy dependence of the P_T-integrated cross section of directly produced quarkonia in pp collisions at next-to-leading order (NLO), namely up to alpha_s^3, within…
