  "abstract": "We report on electrical transport measurements through a carbon nanotube quantum dot coupled to a normal and a superconducting lead. The ratio of Kondo temperature and superconducting gap $T_{K}/\\Delta$ is identified to govern the transport properties of the system. In the case of $T_{K}<\\Delta$ the conductance resonance splits into two resonances at $\\pm \\Delta$. For the opposite scenario $T_{K}>\\Delta$ the conductance resonance persists, however the conductance is not enhanced compared to the normal state due to a relative asymmetry of the lead-dot couplings. Within this limit the data is in agreement with a simple model of a resonant SN-interface.",
