Charge-conjugation asymmetry and molecular content: the $T_{cc}(3875)$ and $D^*_{s0}(2317)$ in nuclear matter
Year: 2025
Type: conference-paper
Abstract: We show how the nuclear environment modifies the spectral functions of the 𝑇𝑐𝑐(3875) and the 𝐷𝑠(2317) exotic hadrons. These states do not have well defined charge-conjugation, and the medium breaks 𝐶−parity symmetry and induces different particle-antiparticle line-shapes. If these distinctive density dependencies were confirmed experimentally, it would give support to the presence of important molecular components in these exotic resonances. This is because if these hadrons were mostly compact four-quark structures, the density behavior of their line-shapes in the medium, while certainly different, would probably not follow the same patterns found in molecular scenarios.
