Abstract
We illustrate the use of recursion relations in the computation of certain one-loop helicity amplitudes containing an arbitrary number of gauge bosons. After a brief review of the recursion relations themselves, we discuss the resolution of the apparent conflict between the spinor helicity method used to solve the recursion relations and the dimensional regulator used in the loop integrals. We then outline the procedure for constructing loop amplitudes, and present two examples of results obtained in this manner.
