    "abstract": "The Density Dependent Relativistic Hadron Field (DDRH) theory, previously\nintroduced and applied to isospin nuclei, is extended to hypernuclei by\nincluding the octet hyperons. Infinite matter Dirac-Brueckner theory for octet\nbaryons and the derivation of in-medium DDRH baryon-meson vertices is\ndiscussed. From the properties of Dirac-Brueckner interactions it is found that\nhyperon and nucleon self-energies and vertices are related by the ratios of\nfree space coupling constants. This leads to simple scaling laws for the\nin-medium hyperon and nucleon vertices. The model is applied in relativistic\nDDRH mean-field calculations to singl$\\Lambda nuclei. Free space N-Lambda\nT-matrix results are used for the scalar vertex. As the only free parameter the\nhyperon vector vertex scaling factor is adjusted to a selected set of\nhypernuclear data. Spectroscopic data of single Lambda hypernuclei over the\nfull mass range are well described. The reduced Lambda spin-orbit splitting is\nreproduced and found to be related closely the medium dependence of scalar and\nvector interactions.",
