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].
