description

The K¯∗ meson in dense matter is analyzed by means of a unitary approach in coupled channels based on the local hidden gauge formalism. The K¯∗ self-energy and the corresponding K¯∗ spectral function in the nuclear medium are obtained. We observe that the K¯∗ develops a width in matter up to five times bigger than in free space. We also estimate the transparency ratio of the γA→K+K∗−A′ reaction. This ratio is an excellent tool to detect experimentally modifications of the K¯∗ meson in dense matter.
