Abstract
We introduce a scalar and a vector DELTADELTA-meson vertex in the rela tivistic Dirac-Brueckner model for nuclear matter and investigate the consequences. We find small effects on the effective nucleon propertie s. The effects in the DELTA sector are more profound, although the DEL TA is still effectively repelled out of the medium.
