| 英文摘要 | Considering the possibility to build an e (+) e (-) collider at the energies around Z-boson resonance with a luminosity so high as L ae 10(34) cm(-2) s(-1) (even higher) and the abilities of a modern synthesis detector, we systematically calculate the exclusive two body processes of the heavy quarkonium production: e (+) e (-) annihilates into a heavy quarkonium and a photon, involving the initial state radiation (i.e. ISR) cases, at the energies around the Z-boson resonance. Since the couplings of Z-boson to quarks contain an axial vector term as well as a vector one, a charmonium such as J/psi or eta (c) or h (c) or chi (cJ) aEuro broken vertical bar, or a bottomonium such as I' or eta (b) or h (b) or chi (bJ) aEuro broken vertical bar, associating with a photon, may be produced respectively via Z-boson annihilation. If we call such a collider with so high luminosity and running around the Z-boson resonance as a Z-factory, then our results obtained here indicate that experimental studies of the various heavy quarkona (their ground and excited states) via the two-body processes at a Z-factory have outstanding advantages, especially, the production of the possible states with quantum numbers J (PC) = 1(--) via ISR. |
