(K)over-bar* meson in nuclear matter

The properties of the (K) over bar* 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 (K) over bar* spectral function in the nuclear medium and we found that the (K) over bar* develops an in-medium width up to five times bigger than in free space. We also estimate the transparency ratio of the gamma A -> K+K*(-) A' reaction, which we propose as a feasible experimental scenario to detect in-medium modifications of the (K) over bar* meson.
