Cross sections for two final states are extracted with $>3\sigma$ sensitivity.

In Koch et al. [Phys. Rev. C 110, 025201 (2024)], the authors construct a model for nuclear matter which features a quarkyonic phase. A main feature in this model is that the nucleon occupation is strongly reduced at small momenta. Somewhat surprisingly, this result is supported in comparison with d…
