\begin{itemize} |

\item Collect a set of particle-flow objects consistent with a |

hadronic tau decay. |
| 8 |

\item Merge photon pairs into candidate neutral pions and compute the decay mode of |

the tau candidate. |
| 10 |
< |
\item Remove objects that are consistent with underlying event |

contamination. |

\item Apply a discriminant \emph{specific to the reconstructed |

decay mode} to the tau candidate. |
