Lunedi 26 Marzo: EWK meeting Introduction and currrent status Giuseppe Baglisi Preliminary L1 results on Z->tautau Simone Gennai Past results on tau tagging efficiency from data Alexandre Nikitenko Z->tautau -> leptons Kajari Mazumdar Z->tautau->mu + tau-jet Nicola De Filippis What can we learn from Z->, W-> channels? Z-> understand isolation algorithms, trigger, JET energy calibration –background for A/H-> tagging efficiency from data W-> understand isolation, MET calibration, trigger –Benchmark for H + -> (but much lower E T involved) – Check W-> brancing ratio Masses and energy scale are different but the SM processed should/must be understood before any search or discovery claim AGENDA

G. Bagliesi – EWK meeting 26/03/ How tau decays are identified Only hadronic tau decays are considered since the leptonic tau decays produce standard electrons/muons –Identification through the final lepton tau tagging basic ingredients –Calorimetric isolation and shape variables –Charged tracks isolation –Other methods (IP, Decay lenght, Mass tag) Main background for taus –QCD jets –Electron that shower late or with strong bremstrahlung –Muons interacting in the calorimeter - PT of the Leading Track (i.e. highest pT track) must exceed a few GeV/c - Leading Track must be found inside the Matching cone
