Title: Exclusive processes e{sup +}e{sup -}{yields}VP in k{sub T} factorization

Abstract

The exclusive processes e{sup +}e{sup -}{yields}VP, in the region of which the final state meson momentum is much larger than the hadronic scale {lambda}{sub QCD}, are studied in the framework of the perturbative quantum chromodynamics (PQCD) approach based on the k{sub T} factorization. Including the transverse momentum distribution in the light-cone wave functions, our results are consistent with the experimental measurements. According to our results, many processes have large enough cross sections to be detected at {radical}(s)=10.58 GeV. The s dependence of the cross section has been directly studied and our result indicates that the 1/s{sup 3} scaling is more favored than 1/s{sup 4}. We also find that the gluonic contribution for the processes involving {eta}{sup (')} is tiny.
