Key Details

Quark model couples bare states to meson-meson channels

Resulting mass shifts match Ds1(2536) and Ds1(2460) mesons

Mixing angle between states emerges close to ideal

No fine-tuning of mixing angle needed, contrary to some claims

Other axial-vector and lattice results also do not favor molecular picture

AI generated summary

Quark model explains axial-vector charm-strange mesons

A published quark model study shows the axial-vector charm-strange mesons Ds1(2536) and Ds1(2460) naturally emerge without fine-tuning, arguing against a molecular interpretation. Additional mesons and lattice results also do not support the molecular scenario.
