Status of Monte Carlos for a tau pair production at SLC

The Monte Carlos for tau-pair production at the SLC, including spin effects and polarized beams, are in good shape. There are two quite independent, fairly complete Monte Carlos KORALZ and LUND/tau. The main limitation of both Monte Carlos at this point is the lack of higher multiplicity decay modes. The addition of these modes is in progress for both Monte Carlos. It is not necessary that all spin effects be included for these modes. The predictions of the two Monte Carlos are in agreement with each other and with theoretical predictions within statistical errors. More precise checks will be made with more statistics in the future
