摘要
We investigate the associated production of heavy quarkonia, with angular-momentum quantum numbers L-2S+1(J)=S-1(0),S-3(1),P-1(1),P-3(J) (J=0,1,2), and photons, Z bosons, and W bosons in photon-photon, photon-hadron, and hadron-hadron collisions within the factorization formalism of nonrelativistic quantum chromodynamics providing all contributing partonic cross sections in analytic form. In the case of photoproduction, we also include the resolved-photon contributions. We present numerical results for the processes involving J/psi and chi(cJ) mesons appropriate for the Fermilab Tevatron, CERN LHC, DESY TESLA, operated in the e(+)e(-) and gammagamma modes, and DESY THERA.
