The Tau Neural Classifier algorithm reconstructs the decay mode of the
|

friis |
1.5 |
tau--candidate and then feeds the tau--candidate to a discriminator associated
|
3 |
|
|
to the decay mode to make the classification decision. Each discriminator
|
4 |
|
|
therefore maps to a reconstructed decay mode in a one-to-one fashion. To
|
5 |
|
|
optimize the discrimination for each of the different decay modes, the TaNC uses
|
6 |
|
|
an ensemble of neural nets. Each neural net corresponds to one of the dominant
|
7 |
|
|
hadronic decay modes of the tau lepton. These selected hadronic decays
|
8 |
|
|
constitute 95\% of all hadronic tau decays. Tau--candidates with reconstructed
|
9 |
|
|
decay modes not in the set of dominant hadronic modes are immediately tagged as
|
10 |
|
|
background.
