Tau identification performance measurements in data

Complete: 1

Structured Offline Guide common to all pages in this guide



This task force is aimed at providing and optimizing measurement of tau identification efficiencies in real data. As the identification path consists of several steps including triggering, cuts and selection, it can split down into different topics such as:

  • energy response/resolution
  • isolation cuts (charged/neutral)
  • jet shapes ( energy dependant)
  • distinction of low/high-pT regimes
  • trigger
  • conversions
  • ...

Optimization procedures (esp. isolations) should involve a luminosity dependence approach


Algorithms and Software Architecture

Analysis and Validation

  • Measurement of tau-identification efficiency from Z->ee/Z->etau events. K. Petridis and S. Greder. Based on CMS NOTE 2006/074
  • Measurement of tau-identification efficiency from Z->ee/Z->mutau events. ????? ( needs urgently someone)




(see also presentations in Meetings section)

CMS Notes:

  • CMS NOTE 2006/074, "Measurement of the τ tag efficiency using the Z → τ τ → µ + hadrons + X events"
