Robustness of a SiECAL used in Particle Flow Reconstruction
  The physics program of future lepton colliders such as the ILC, will benefit from a jet energy resolution in the range 3-4%. The International Large Detector (ILD) reaches this goal over a large range of jet energies. In this paper, we report on the dependence of the simulated ILD performance on various parameters of its silicon-tungsten ECAL. We investigate the effects of dead areas in the silicon sensors, the thickness of the PCB at the heart of the detector, and the robustness of its performance with respect to dead channels, noise, mis-calibration and cross-talk.
