Distributions for CMX W and Z decay candidates

Detector Eta

These plots were made in response to the question "why do my eta plots look so screwy". The answer to the question was: " You didn't reprocess with the post-production drift constants." (See CDF note 2332.) Detector eta is computed from the muon stub r and z postion.
  • CMX detector eta for 1A W decay candidates after processing with the run-dependent drift constants.
  • CMX detector eta for 1B W decay candidates processed without run-dependent drift constants.
  • CMX detector eta compared for 1A and 1B W decay candidates. The title on the plot is somewhat misleading; the hatched histograms are 1B while the solid are 1A. This shows the effect of getting the drift velocity right.
  • CMX detector eta for various hit cuts (1A W decay candidates, reprocessed). In the plots, the boxes show the ideal detector eta.

    This data comes from the IA W sample. No other cuts have been made.
