bar K* meson in nuclear matter

The properties of the bar K* meson in dense matter are studied using a unitary approach in coupled channels within the framework of the local hidden gauge formalism. We obtain the bar K* spectral function in the nuclear medium and we found that the bar K* develops an in-medium width up to five times bigger than in free space. We also estimate the transparency ratio of the γA → K⁺K^*-A' reaction, which we propose as a feasible experimental scenario to detect in-medium modifications of the bar K*meson.
