| 英文摘要 | In the paper, the inclusive production of heavy quarkonium eta(Q) (Q = b or c) via Z boson decays within the framework of nonrelativistic QCD effective theory are studied. The contributions from the leading color-singlet and color-octet Fock states are considered. Total and differential decay widths for the inclusive decays Z -> eta(Q) + X are presented. It is found that the decays Z -> eta(Q) + X arc dominated by the S-3(1)[8] component, so the decays can be inversely adopted to determine the values of the long-distance matrix elements < O-eta c(S-3(1)[8])> and < O-eta b(S-3(1)[8])>, respectively. Our numerical results show that at an e(+)e(-) collider running at the Z pole with a high luminosity around 10(35) cm(-2) s(-1) (a super Z factory), there are about 4.5 x 10(7) eta(c) meson events and 6.1 x 10(5) eta(b) meson events to be produced per operation year, and the inclusive decays may be used for clarifying some problems on the heavy quarkonium eta(Q) and nonrelativistic QCD. |
