Nearly 60 years ago Weinberg suggested a criterion for particle "compositeness", which has acquired new life with the discovery of new, exotic hadrons. His idea resonates with model-based intuition. I discuss the role it plays in the context of another of Weinberg's creations, the model-independent framework of effective field theories.

Determining the width of $D_{s0}^{*}(2317)$ by using $T_{c\bar{s}0}^{a}(2327)$ in a molecular frame
hep-ph 2025-07 conditional novelty 5.0 of 10

Calibrating the DK molecular model on the newly measured Tcs0(2327) width predicts the Ds0*(2317) width to be 63 to 209 keV.
