| dc.description | Recent experimental observation by the CBELSA/TAPS collaboration indicates a downward mass shift of the $ω$ meson when put into a nuclear medium. Therefore it is worthwhile to take a look at theoretical approaches that can describe this mass shift. One such hadronic model was introduced by Klingl et al. (Nucl.Phys. A650:299-312). We will demonstrate that the heavy baryon limit approximation used there has no justification and returns wrong results. The results obtained with a correct treatment of the relevant $2π$-channel lead to unreasonable results for the $ω$ selfenergy in medium. | |
