On next-to-eikonal exponentiation
arXiv:1007.0624 · doi:10.1016/j.nuclphysbps.2010.09.003
Abstract
The eikonal approximation is at the heart of many theoretical and phenomenological studies involving multiple soft gauge boson emissions in high energy physics. We describe our efforts towards the extension of the eikonal approximation for scattering amplitudes to the first subleading power in the soft momentum.
