Recent progress on charmed hadron interactions from lattice QCD

Abstract

Recent years have witnessed rapid progress in charmed hadron physics, driven by numerous experimental discoveries of exotic states such as $T_{cc}^{+}$ and $P_c$. These findings have highlighted the importance of understanding charmed hadron interactions. With significant advances in theory and computation, lattice QCD has become a reliable tool for studying nonperturbative dynamics of low-energy QCD. In this talk, I review recent lattice QCD studies of charmed hadron interactions, focusing on three representative systems: $D^{\ast }$-$D$, $N$-$c\bar{c}$, and $\hat{I}{\text{c◯}}_{ccc}$-$\hat{I}{\text{c◯}}_{ccc}$.
