Path integral approach to eikonal and next-to-eikonal exponentiation

  title={Path integral approach to eikonal and next-to-eikonal exponentiation},
  author={Eric Laenen},
We approach the issue of exponentiation of soft gauge boson corrections to scattering amplitudes from a path integral point of view. We show that if one represents the amplitude as a first quantized path integral in a mixed coordinate-momentum space representation, a charged particle interacting with a soft gauge field is represented as a Wilson line for a semi-infinite line segment, together with calculable fluctuations. Combining such line segments, we show that exponentiation in an abelian… CONTINUE READING
