Abstract:

We present a novel approach to partial-wave unitarity that bypasses a lot of technical difficulties of previous approaches. In this method we use the harmonic numbers as a basis. Owing to the properties of the harmonic numbers this method can be used to derive a clear and unified form for the partial-wave coefficients. We use the Coon amplitudes and its limit to exemplify this approaches and show how it allows to make important properties such as partial-wave unitarity manifest.
