Associated production of Y and weak gauge bosons in hadron colliders - art. no. 091501

We calculate the rate of production of W+/- + Y and Z(0) + Y in hadron coll iders. We find the cross sections for W+/- + Y and Z(0) + Y to be roughly 0 .45 pb and 0.15 pb at the Fermilab Tevatron and roughly 4 pb and 2 pb at th e CERN Large Hadron Collider (LHC). The dominant production mechanism invol ves the binding of a color-octet <b(b)over bar> pair into a P-wave bottomon ium state which subsequently decays into Y. The purely leptonic decay modes of Y, W+/-, and Z(0) provide signatures with small backgrounds. These even ts may be observable in run II at the Tevatron, and they should certainly b e observable at the LHC. [S0556-2821(99)50317-2].
