摘要：

We investigate the O(alpha(s)v(2)) correction to the e(+)e(-) -> J/psi + eta(c) process in the nonrelativistic QCD ( NRQCD) factorization approach. Within some reasonable choices of the relative order-v(2) NRQCD matrix elements, we find that including this new ingredient of correction only mildly enhances the existing NRQCD predictions. We have also deduced the asymptotic expressions for the O(alpha(s)v(2)) short-distance coefficients, and reconfirm the early speculation that at next-to-leading order in alpha(s), the double logarithm of type ln(2)(s/m(c)(2)) appearing in various NRQCD short-distance coefficients is always associated with the helicity-suppressed channels.
