Abstract

We calculate the rate of production of W± + γ and Z0+γ in hadron colliders. We find the cross sections for W± + γ and Z0 + γ to be roughly 0.45 pb and 0.15 pb at the Fermilab Tevatron and roughly 4 pb and 2 pb at the CERN Large Hadron Collider (LHC). The dominant production mechanism involves the binding of a color-octet bb̄ pair into a P-wave bottomonium state which subsequently decays into γ. The purely leptonic decay modes of γ, W±, and Z0 provide signatures with small backgrounds. These events may be observable in run II at the Tevatron, and they should certainly be observable at the LHC.
