Comparison of integral equations used to study $T_{cc}^{+}$ for a stable $D^{\ast }$

Sebastian M. Dawid, Fernando Romero-López, Stephen R. Sharpe

We perform a detailed comparison between three formalisms used in recent studies of $D{D}^{\ast }$ scattering, which aim to understand the properties of the doubly-charmed tetraquark, $T_{…
