On the eikonal unitarisation at high energies
arXiv:1309.5860
Abstract
We consider approaches to the eikonal-like unitarization of elastic amplitude and its generalizations in theories where cross-sections grow with energy, and we discuss corresponding mechanisms of the multiple exchange standing behind it. In particular, we argue that in such theories the weight of the -fold exchanges can grow with much faster than for the simplest Glauber eikonal.
