Recursive algebraic equations are derived and determine the amplitudes; all loop integrations are performed. This recursion contains the same information as the usual loop expansion. The approach is pragmatic and generalizable to most quantum field theories.8 pages, 1 figureHigh Energy Physics - TheoryHigh Energy Physics - Phenomenologytext
