Both methods were separately optimised for decays with one charged particle (1-prong) and three charged particles (3-prong). Furthermore the optimisation was splitted into five Et bins:
We used Pythia Z->tautau and bbA(800)->bbtautau (for high pT taus) samples as signal and several Pythia di-jet samples with a momentum transfer at hard scatter ranging from 17 - 560 GeV for the background.
Three types of optimisation are defined for each method:
The plots on this page show the distribution of the identification variables for signal and background in the Et bin 25 - 45 GeV for 1-prong and 3-prong tau candidates. Futhermore the performance for both methods is shown, separately for both decay modes (1-prong and 3-prong) and all five Et bins.
