Study of exclusive processes e^+ e^- \to VP

Abstract

This paper is devoted to consideration of the hard exclusive processes $e^{+}{e}^{-}\to VP$, where $V=\rho ,\varphi ;P=\eta ,{\eta }^{\prime }$. Experimental measurement of the cross section of the process $e^{+}{e}^{-}\to \varphi \eta$ at BaBar collaboration at large center mass energy $\sqrt{s}=10.6$ GeV and some low energy experimental data $\sqrt{s}\sim 2-4$ GeV give us the possibility to study the cross section in the broad energy region. As the result, we have determined the asymptotic behavior of the cross section of $e^{+}{e}^{-}\to \varphi \eta$ in the limit $s\to \infty$, which is in agreement with perturbative QCD prediction. Assuming that the same asymptotic behavior is valid for the other processes under consideration and using low energy experimental data we have predicted the cross sections of these processes at energies $\sqrt{s}=3.67,10.6$ GeV. In addition, we have calculated the cross sections of these processes at the same energies within perturbative QCD. Our results are in agreement with available experimental data.
