Study of the colour singlet model with k_T-factorization in inclusive J/\psi production at CERN LEP2

We calculate the cross section and the transverse momentum distribution of inclusive J/\psi production in \gamma \gamma collisions at CERN LEP2 within the colour singlet model and the k_T-factorization approach, including both direct and resolved photon contributions. The unintegrated gluon distribu...

description We calculate the cross section and the transverse momentum distribution of inclusive J/\psi production in \gamma \gamma collisions at CERN LEP2 within the colour singlet model and the k_T-factorization approach, including both direct and resolved photon contributions. The unintegrated gluon distribution in the photon is determined, using the Blumlein's prescription for unintegrated gluon distribution in a proton. We compare our theoretical predictions with preliminary data taken by the DELPHI collaboration at LEP2. In addition, we present our predictions for the J/\psi polarization properties.
