| Abstract: | We study ?-meson production in nuclei to investigate the in-medium modification of the ?-meson spectral function at finite density. We consider ( ${\bar p},\phi$ ), (γ,p) and (π ???, n) reactions to produce a ?-meson inside the nucleus and evaluate the effects of the medium modifications to reaction cross sections. The structures of the bound states, ?-mesic nuclei, are also studied. For strong absorptive interaction cases, we need to know the spectrum shape in a wide energy region to deduce the properties of ?. |
