Synergy of combined LHC and LC Analyses in Susy Searches
  We present a case study for the synergy of combined LHC and LC analyses in Susy searches where simultaneous running of both machines is very important. In case that only light non-coloured Susy particles are accessible at a Linear Collider with an initial energy of $\sqrt{s}=500$ GeV, the precise analysis at the LC nevertheless leads to an accurate Susy parameter determination. This allows the prediction of heavy Susy particles. Providing these LC results as input for LHC analyses could be crucial for the identification of signals resulting in a direct measurement of the heavy neutralinos. These results provide an important consistency test of the underlying model. Furthermore, feeding back the LHC results into LC analyses leads to an improvement in the parameter determination.
