====== TTP96-46 Effective Field Theory for a Heavy Higgs Boson: Matching and Gauge Invariance ====== For large values of the Higgs mass the low energy structure of the gauged linear sigma model in the spontaneously broken phase can adequately be described by an effective field theory. We present a manifestly gauge-invariant functional technique to explicitly evaluate the corresponding effective Lagrangian from the underlying theory. |**Andreas Nyffeler and Andreas Schenk** | |** Proceedings of the 1996 Annual Divisional Meeting (DPF 96) of the Division of Particles and Fields of the American Physical Society, 11-15 Aug 1996, Minneapolis, Minnesota.
