| 英文摘要 | The cross sections of e(+)e(-) to S-wave and P-wave quarkonia with C-parity even associated with a photon are analyzed in the framework of nonrelativistic Quantum Chromodynamics (NRQCD) factorization formulism. The short-distance coefficients are analytically determined up to the next-to-leading order (NLO) QCD radiative corrections to S-wave and P-wave quarkonium production and NLO relativistic correction to eta(c) production. We also invoke the analytical expressions to estimate the cross sections. Our numerical results indicate that both the QCD and the relativistic corrections are considerable. |
