Inclusive vector charmonium production in two-photon e^+ e^- -annihilation at \sqrt{s}=10.6 GeV

Abstract

In this paper we study inclusive production of vector charmonium states $J/\psi$ or $\psi (2S)$ in two-photon $\text{epem}$-annihilation at $\sqrt{s}=10.6\mathrm{GeV}$ using color-singlet model. Analytic expressions for differential cross sections, numerical values of total cross sections and plots of different distributions are presented. These distributions differ significantly from the one-photon case so these modes can be easily separated.
