Coon unitarity via partial waves or: how I learned to stop worrying and love the harmonic numbers
arXiv:2401.13031 · doi:10.1103/PhysRevD.110.126024
Abstract
We present a novel approach to partial-wave unitarity that bypasses a lot of technical difficulties of previous approaches. In passing, we explicitly demonstrate that our approach provides a very suggestive form for the partial-wave coefficients in a natural way. We use the Coon amplitudes to exemplify this method and show how it allows to make important properties such as partial-wave unitarity manifest.
