A variation on "compositeness" (including higher partial waves)

TL;DR

This paper extends the concept of compositeness, originally developed for non-relativistic potential scattering, to include higher partial waves, offering a new perspective on its derivation and interpretation.

Contribution

It introduces a modified approach to the spatial interpretation of compositeness applicable to higher partial waves, providing a novel viewpoint in the theoretical framework.

Findings

Extended the spatial interpretation of compositeness to higher partial waves

Provided a new basis for deriving and understanding compositeness

Offered insights that could refine the analysis of scattering states

Abstract

The ``spatial interpretation of compositeness'', presented and discussed in [1,2] in the context of non-relativistic potential scattering, is extended to higher partial waves. A particular set of basis states is used to arrive at a slightly different perspective on the derivation and interpretation of ``compositeness'' usually given in the literature.
