Hard and soft QCD in charmonium production
- 2000
-
Conference paper (other academic/artistic)abstract
- We show that both hard perturbative and soft non-perturbative QCD effects are important in hadroproduction of charmonium. Observed $x_F$ and $p_\perp$ distributions of J/psi in fixed target experiments can be well described by our Monte Carlo model based

Journal article (peer-reviewed)abstract
- Both hard and soft QCD dynamics are important in charmonium production, as presented here through a next-to-leading order QCD matrix element calculation combined with the color evaporation model. The observed $x_{\mathrm{F}}$ and $p_\perp$ distributions o

Journal article (peer-reviewed)abstract
- The diffractive photoproduction of vector mesons is usually described by considering the two-gluon (Pomeron) exchange, the nondiagonal parton distributions, and the contribution of the real part to the cross section. In this Brief Report we analyze the di
