abstract
We demonstrate that the propagator, derived from an Effective Field Theory (EFT) that incorporates Weinberger's compositeness theorem, provides a more general formula for describing S-wave near-threshold states. By fitting the lineshape using this propagator, we can extract the $Z$ factor for these states and elucidate their structures.

Compositeness relations for near-threshold p-wave bound states
The paper derives p-wave compositeness relations a1 = 2(Z-1)/(Z+2) * 1/(2μB)^{3/2} and r1 = 3Z/(1-Z) sqrt(2μB) using a nonrelativistic effective field theory.
