Reparameterization Invariance in Heavy Particle Effective Field Theories
Clarence L. Lee
In a low energy effective theory, the fields of heavy particles with mass and total momentum depend on both a velocity and a residual momentum such that .…

Heavy Particle Effective Field Theories
Clarence L. Lee
Starting from a theory of heavy particles and antiparticles, the path integral formulation of an effective field theory which describes the low momentum interactions is presented.…
