Associated Production of Heavy Quarkonia and Electroweak Bosons at Present and Future Colliders
Abstract
We investigate the associated production of heavy quarkonia, with angular-momentum quantum numbers 2S+1LJ = 1S0, 3S1, 1P1, 3PJ (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 chicJ mesons appropriate for the Fermilab Tevatron, CERN LHC, DESY TESLA, operated in the e+ e- and gamma gamma modes, and DESY THERA.
