Indirect Sensitivity to Heavy Z' Bosons at a Multi-TeV e+e- Collider
  We compare the phenomenology of two models, the so-called minimal Z' and an effective model for a SM-like Higgs realised as a composite state of a new strong interaction, at a multi-TeV linear collider in the hypothesis that the new physics is at a scale beyond the direct reach of the machine.
