Compositeness relations for near-threshold p-wave bound states

Abstract

We generalize Weinberg's compositeness relations to near-threshold p-wave bound states and derive the relations between the p-wave effective range expansion parameters, binding energy B, and the field renormalization constant Z. We also provide the corresponding Feynman rules which are appliecable regardless of whether the near-threshold state is a pure molecular state or an elementary multiquark state.
