15 Aug 2000 | | Journal: | Nucl.Phys. A689 (2001) 753-783 | | Subject: | nucl-th hep-ph | | Affiliation: | Universität Giessen | | Abstract: | We calculate the spectral function $A_
ho$ of the $
ho$ meson in nuclear matter. The calculation is performed in the {it low density} approximation, where the in-medium self energy $Sigma_{med}$ is completely determined by the vacuum $
ho N$ forward scattering amplitude. This amplitude is derived from a relativistic resonance model. In comparison to previous non-relativistic calculations we find a much weaker momentum dependence of $Sigma_{med}$, especially in the transverse channel. Special attention is paid to uncertainties in the model. Thus, we compare the impact of different coupling schemes for the $RN
ho$ interaction on the results and discuss various resonance parameter sets. | | Source: | arXiv, nucl-th/0008027 | | Services: | Forum | Review | PDF | Favorites | |
