Particle Identification in 4th
  We describe 12 measurements in the 4th detector that yield particle identification information. Seven of these have been demonstrated with test beam data from the DREAM collaboration, one demonstrated in cosmic muon test data, one verified in ILCroot, and the remaining three will be tested in ILCroot. Not all are independent, but as a whole they cover all partons of the standard model.
