Tau identification commissioning result

CMS has developed sophisticated tau identification algorithms for tau hadronic decay modes. Production of tau lepton decaying to hadrons are studied at 7 TeV centre of mass energy with 2011 collision data collected by CMS detector and has been used to measure the performance of tau identification algorithms by measuring identification efficiency and mis-identification rates from electrons, muons, and hadronic jets. These algorithms enable extended reach for the searches for MSSM Higgs , Z' and other exotic particles.
