Effective Field Theory for a Heavy Higgs: a Manifestly Gauge Invariant Approach

For large values of the Higgs boson mass the low energy structure of the ngauged linear sigma model in the spontaneously broken phase can adequately be ndescribed by an effective field theory. In this work we present a manifestly ngauge invariant technique to explicitly evaluate the corresponding effective nLagrangian from the underlying theory. In order to demonstrate the applicat..
