摘要：

Using the nonrelativistic QCD factorization formalism, we calculate the electroproduction cross sections of eta(c) in ep collisions, including the contribution from both the transverse photon and the Longitudinal photon. For this process the color-singlet contribution vanishes up to the next to Leading order perturbative QCD calculations. The dominant contribution comes from the color-octet S-1(0)(8) subprocess The nonperturbative color-octet matrix element of S-1(0)(8) of eta(c) is related to that of S-3(1)(8) of J/psi by heavy quark spin symmetry, and the fatter can be determined from the direct production of J/psi at large transverse momentum at the Fermilab Tevatron. The measurement of this process at DESY HERA can be viewed as another independent test for the color-octet production mechanism.
